Rod, pipe, wire made of 2.1020CuSn6

Technical characteristics

2.1020CuSn6 relates to a class of tin bronze that can be pressure-treated. Industrial use: screws, shafts, wear-resistant bushings, bearings, pump components.


Tin bronzes have increased anti-friction qualities. They are non-magnetic, cold-resistant, insensitive to overheating, have a minimum volumetric shrink-off (approximately 0.8%). Due to this, it is widely used in art casting. The main demerit of tin bronzes is formation of small reeds in castings, which can disrupt it hydraulic soundness. Tin bronzes are alloyed with plumb, zinc, nickel, phosphorus.


Solid solution forms during a process of copper and tin melting. It is prone to segregation because of a high temperature interval of crystallization. Alloys that contain more than 5% of tin possess a segregation because of eutectoid component E (a + d), which consists of hard and soft phases.

Main properties

Structure of this alloy is beneficial for parts of sleeve bearings: solid particles provide wear resistance. Soft phase gives excellent conformability due to which tin bronzes are excellent anti-friction materials.

Coefficient of friction with lubricant = 0.01

Coefficient of friction without lubricant =0.12

Alloy hardness: HB 10 -1 = 70 — 90 MPа

Point of melting = 995°C
