Product lineup
Beryllium Copper Material
We offer in plate and round bar shapes.They are mainly manufactured by forging and drawing, supplyied size is following.
Plate: max. t300mm × w600mm × L1200mm
Round bar: Max. φ200mm × L1000mm
Chill Vents
Our chill vents offer high thermal conductivity to enable the setting of ample clearances. They help improve gas exhaust efficiency and increase product yields.
In addition, since vent lengths can be made shorter than with SKD materials, they make compact designs possible.
Wrought Products
Beryllium copper alloy offers various superb characteristics, including mechanical strength, wear resistance, and corrosion resistance. Parts made of this alloy are widely used in aircraft, construction machinery, and submarine repeater casings.
We offer the products in customer-specified shapes and dimensions.
Beryllium Copper Strips
Our mainstay products, beryllium copper strips, are supplied in sheet, strip, or rod form. The material offers an optimal combination of mechanical and physical properties, including mechanical strength, thermal conductivity, fatigue strength, thermal behavior, machinability, and corrosion resistance, making it ideal for various springs.
Regulations and Safety of Beryllium Copper
Regulations
Our standard beryllium copper (an alloy containing 2% or less beryllium) is not regulated under the Japanese Industrial Safety and Health Law, the Ordinance on Prevention of Hazards due to Specified Chemical Substances, and EU chemical substance regulations such as REACH, RoHS, and ELV.
Safe
When commonly used beryllium copper is handled in its solid state or as a finished product, during pressing, machining or bending, it poses no health risk and requires no special hygiene considerations.
On the other hand, if fumes or fine dust are generated during melting/casting, spark erosion, welding, dry grinding/polishing, considerations such as ventilation and the wearing of masks are required, as with general metals.
