CC 483K / CuSn12

Tinbronze.

CuSn12 has higher mechanical values than Rg7. Adding tin and using less zinc and lead makes a harder and tougher alloy. Tinbronze is corrosion and seawater resistant and often used in the marine industry. High wear resistance even at higher speeds makes this alloy suitable for bearings with high slide speed and heavy load capacity. Lubrication with regular intervals is important for this alloy.

Areas of use:
Bearings for high sliding speed. Heavy duty worm wheels and spindles and much more.

Delivery program
Solid round bar, tube, square, rectangle and hexagon bar
