High-quality sheet materials and wires for use as basic materials in electrical metal parts are manufactured in our comprehensive in-line production system, which capitalizes on our accumulated experience and technological prowess. For production of sheet materials, raw materials are melted at high temperatures to make an alloy that has the desired ingredients. Then, the alloy is given the required specific properties and dimensions through such processes as hot and cold rolling and heat treatment. In production of clad metals, polished metals are stacked and passed through roll cladding and rolling processes. The bonding between the metals is reinforced by annealing and the resultant clad metal is processed in the same way as ordinary plates. Finally, the product is slit to the desired width. To produce wires, raw materials are melted at high temperatures into an alloy with the required ingredients. Then, the alloy undergoes hot rolling, cold drawing through dies, annealing and peeling; these processes are repeated until the product is finished to the required properties and dimensions.

Coutions regarding Product Use

MAGNETIC MATERIALS 1. To ensure that the materials display their true magnetic properties, magnetic annealing should be performed as specified after the components have been machined as

prescribed.

2. Deformation or distortion after magnetic annealing could cause deterioration of the magnetic properties or other problems, so parts should be handled with care after

annealing.

3. The magnetic property values listed in the catalog are values measured using a ring-shaped sample with a closed magnetic circuit. Designing components based on the

assumption that these values are absolute could result in problems. Component design should always take info consideration how the shape of the component will affect the magnetic properties.

KV 1. Fe-Ni-Co alloy causes phase transformation under cryogenic temperature.

Consult manufacturer before using material under cryogenic temperature. Note: Cryogenic temperature (73K 195K)

2. When Fe-Ni-Co alloy is brazed with silver brazing filler metal under tensile stress silver brazing filler metal penetrates along the grain boundaries of Fe-Ni-Co alloy and the

penetration may cause Fe-Ni-Co alloy to be cracked. Fe-Ni-Co alloy shall not be brazed with silver brazing filler metal under tensile stress otherwise Fe-Ni-Co alloy shall be Ni-plated before brazing process.

3. When Fe-Ni-Co alloy series is exposed to corrosive environment (especially chorine) under tensile stressed condition stress corrosion cracking may happen.

Any corrosive substance (especially plating liquid) shall not be left and the residual stress or strain shall be minimized after sealing.

CLAD METAL 1. The bonding strength of composite panels varies according to the combination of materials used. Separation may occur if the panel is subjected to bending,twisting, or

application of other forces which exceed the bonding strength. For this reason, care should be exercised with regard to processing requirements. Please note that additional heat treatment may weaken the bonding strength for some material combinations.

2. Be careful not to confuse the front and rear faces of asymetric composite panels, as correct orientation is essential to gain the required benefits. 3. Some electrolytic corrosion is unavoidable with composite panels as they are a combination of different types of metal. Protective measures are required, especially around

exposed edges where such corrosion is most likely to occur.

BIMETAL 1. If a bimetal is used outside the specified allowable temperature range given in the brochure, problems can result due to malfunction. Make sure that the bimetal is used

within the specified allowable temperature range

2. If a bimetal is used without prior heat treatment (aging) to remove residual stress generated in the cold rolling and molding processes, its initial position or action point

can change during use, compromising dimensional accuracy and, giving rise to problems. If any molding work is applied to the bimetal, use it only after aging.

3. If the stress generated in a bimetal by inherent reactive force, applied restriction, and/or external force exceeds the allowable stress limit during use or product assembly,

plastic deformation of the bimetal can result. Since this can cause malfunction, design your product in such a way as to eliminate stress in excess of the allowable limit for the bimetal.

4. Fins remaining on a bimetal after press molding or cutting can restrain movement and become a source of problems. Make sure that no fins remain by, for instance,

removing them before use.

5. A bimetal can be used after a thin metal film is formed on its surface through, for instance, plating. If the film is too thick, however, movement may be restricted, altering

the coefficient of curvature or even the volume resistivity. In such a case, be aware that the bimetal may not react in the way it is designed to, giving rise to problems.

6. When a snap-action bimetal is used, be careful not to generate excessive stress in it, since this may alter its reaction temperature. If high reaction frequency is required,

ensure before use that stress is not excessive.

7. If the bimetal's high extension material is high Mn-content alloy or brass, pay special attention to the points of caution listed below. In designing a product using this kind

of bimetal, special arrangements must be made for the part containing the piece, such as making the part airtight. The same precaution applies to safekeeping of the bimetal. (1) If the bimetal is used in a corrosive atmosphere, malfunction may result. (2) If the bimetal is exposed to a corrosive atmosphere when stress is present, it may be damaged by cracking due to corrosion under stress. (3) Some gases emitted by some organic materials and adhesives, such as bond, may accelerate corrosion in Mn alloys. (4) If the bimetal is washed with acid, as for instance in pre-treatment for plating, it may be corroded by chemical reaction with the acid.

Handling of materials

1. The edges and cut ends of sheet, strip, bar, and wire materials can cause cuts similar to a sharp knife, so handle such materials with care. 2. When unpacking or cutting the securing bands on sheet, strip, bar, and wire materials, the bands or ends of the materials can lash out and cause injury unless they are cut

with proper care. Materials with spring-like flexibility in particular may cause injury if rapidly shifted, so handle such materials with care.

3. When unpacking sheet, strip, bar, and wire materials, do so carefully to prevent any danger of the stacked materials toppling. Never attempt to life or carry the materials by

the securing bands; doing so may cause the bands to break, allowing the materials to fall in a disorderly way.

4. Packages of sheet, strip, bar, and wire materials are extremely heavy. In addition to exercising caution to prevent the packages from toppling or falling when they are

carried or transported, care should also be taken to avoid lower back injury due to an attempt to life too much weight.

General notes on design

1. These metals and alloys for electric and electronics applications have all been designed to provide specific functions for designated applications. Use of these products for

any function or application other than those indicated in this catalog could be extremely dangerous. Inquiries should be made beforehand regarding any such use.

2. The material properties listed in this catalog are not guaranteed performance levels. Depending on the dimensions, shape, and conditions under which the metals and alloys

are used, the material properties may very from those listed in this catalog and should be confirmed before use of the products.

Processing and use

1. Metals and alloys are subject to discoloration and rust which could cause a drop in function or other unexpected problems. It is important than the products be stored and

used under the proper environmental conditions. If necessary, rust prevention treatment should be used.

2. Use of these materials under applied stress in a corrosive environment could cause failure of the material as a result of stress corrosion cracking. It is therefore important

to select the appropriate material for the environment in which it will be used and to eliminate residual stress.

3. Metals and alloys are subject to oxidation when heat-treated at high temperatures. If performing subsequent processing such as welding or plating, or if contact resistance

or other problems, during use are anticipated, the oxide film formed during heat treatment should be removed.

4. Brazing or spot welding of the materials could cause deterioration of the material properties or shape distortion at the heat-affected zone and surrounding areas, so be sure

to confirm this beforehand.

5. These materials have directional characteristics, so processing by bending could cause cracking to occur. Whenever possible, processing by bending should be performed

in the direction perpendicular to that in which the material was rolled. If the material must be bent in a direction parallel to the rolling direction, acute bending angles should be avoided.

6. When used under a condition of repeated displacement, fatigue could cause failure of the material to occur. Avoid using the material under a condition of repeated

deformation at a stress in excess of the fatigue strength (fatigue limit).

7. Metal powder generated during processing of the materials is both a danger to health if inhaled and a fire hazard due to its flammability, so care must be taken to deal with

it properly.

Chemical and physical properties

1. Pure nickel and alloys containing nickel can cause skin disease through extended direct contact, so they should be handled with care. 2. When alloys containing cobalt are bombarded with neutrons, radiation with a long half-life will be emitted, so careful consideration should be given to the usage

environment, especially for nuclear energy-related applications.

3. Magnetic materials, sealing materials, and most other metals and alloys (magnetic substances containing iron, nickel, or cobalt) will generate heat when exposed to a highfrequency magnetic field. Care should be taken with regard to any burning or deterioration of material properties that a rise in temperature might cause. In addition, such materials might be attracted to a strong magnet or other magnetic force, possibly resulting in the material being magnetized, deformed, or damaged.
