Main qualities:

Bronze without tin does not contain in its composition scarce tin. They can be substitutes for tin bronzes, as their mechanical, corrosion and technological properties of bronze without tin, they are often superior. Without tin bronze can be beryllium, manganese, aluminum, etc., depending on the primary alloying component. Bronze without tin pressure treated, manufactured in accordance with GOST 18175−78. This standard applies to bronze without tin, which are processed under pressure and designed for the production of workpieces, semi-finished products.

The coefficient of friction with lubrication is 0.013

The coefficient of friction without lubrication is 0.4

Hardness of alloy: HB 10 -1 = 70 — 90 MPa
