Description
Mechanical properties
Characteristic & Application
Aluminium brass ZCuZn25Al6Fe3Mn3:applied for high load and strength ,low speed with corrosion-resistant and wear resistant
working conditions.Like Bridge bearing plates,sliding plates for rubber and plastic mould.
Aluminium bronze ZCuAl9Fe4Ni4Mn2:applied for middle load,strength and speed working conditions,good corrosion-resistant in the air,fresh water and seawater.Like sliding plates and bearing used in ships,wharf handing machine and marine machine.
Tin-bronze ZCuSn5Pb5Zn5:applied for high load and middle speed with corrosion-re-sistant and wear resistant working conditions,like bearing,and sliding plate.
