EU RoHS Directive Conformance Marking

RoHS Ready EU RoHS Directive Conformance Marking

Our beryllium copper alloy products (plate, coil, bar and wire) comply with EU RoHS Directive. We use a voluntary marking which shows conformance to RoHS on our material certificate and in the catalog of products. Conformance has been confirmed with certified internal standards. * Coverage: our beryllium copper alloy products (plate, coil, bar and wire)

Standard Products

Features

Standard Products
1) High Strength
Beryllium Copper attains a high tensile strength to a maximum of 1500N/mm2 so is not likely to bend even under pressure.
2) High Electrical Conductivity
The electrical conductivity of Beryllium Copper is 20 to 60% IACS so can be used as a high current density material.
3) High Fatigue Strength
Beryllium Copper is known to have high fatigue strength against repeated motion, is reliable, and has extremely long-life.
4) Elevated Temperature Properties
Beryllium Copper performs excellently at elevated temperatures so can be used in a wide range of temperatures.
5) Good Formability
Using a solution heat treatment, Beryllium Copper is softened to facilitate complex shaping. After shaping, it can achieve the highest strength with an age-hardening process.
6) Corrosion Resistance
Beryllium Copper is highly resistant to corrosion, so shows less corrosion under a variety of environmental conditions.

Characleristics

Age hardenable material can be formed into complicated shapes and precipitation hardened afterwards. Among Mill-hardened material, which dose not require heat-treatment after stamping or forming, "Type-B" and "Type-S" have especially well-balanced performance in strength and formability.

Mill-hardened Products

Mill-hardened Products

Features

  • Due to a straightening process during manufacturing, Beryllium Copper fine wire requires no further straightening when used.
  • Plated wire, in particular, has excellent solderability.
  • As it is age-hardened during the manufacturing process, Beryllium Copper fine wire is hard enough to avoid deformation under high temperature conditions.
