High Contents of Beryllium Copper

[Features]
High strength: Beryllium Copper 25 alloys are the strongest and hardest among all copper alloys. By applying appropriate heat treatment, they become as strong as special steel and while also possessing excellent springing quality, conductivity, abrasion resistance, and corrosion resistance.

[Main Applications]
Explosion-proof/non-spark tools, electrodes for resistance welding, electrode wheels, welding machine parts (arms, holders, jigs, etc.), submarine table repeater chassis parts, die materials, and bearing materials.

Special High-Strength Brass

[Features]
● Great mechanical properties
● Excellent abrasion resistance
● Excellent heat conductivity
● Good casting performance
● Relatively cheap price
[Main Applications]
Nuts, gears, abrasion-resistant boards, low-speed/high-load sliding parts, large-size bulbs, stems, bushes (bearings), cams, hydraulic cylinder parts, slippers, etc. for mills, and construction machinery parts.

NC Alloys

NC50

[Features]
With the same performance as low contents of beryllium copper alloys, NC50's (Patent No. 3563311) cold-worked drawing products can satisfy the JIS Z3234 Class 3 standards.
They can be used as electrode materials and related jigs as well as in a variety of scenes.
[Main Applications]
Electrodes for resistance welding, chip base, gun arms, and plunger chips.
