Bronze grade Br, ANMC 9−4-4−1 refers to a group of wrought corrosion-resistant tin-bronzes, which are obtained by casting or pressing. Material resistant to liquid chloride environments, as well as cavitation processes, and therefore is used for the manufacture of critical parts of marine vessels. In addition, the alloy used for the production of parts operating in conditions of high wear — shafts, gears, nuts, adjusting screws, bushings bearings, pipe boards capacitors, chemical machinery parts, etc. Alloy has high strength at temperatures up to 300…350°C,
- Density, kg/m3 7700;
- Electrical resistivity at room temperature, оммм2/m — 0,188.
- The limit of temporary resistance, MPa — 540;
- Yield strength, MPa — 260;
- Relative tensile elongation. % — 1,5…4,0;
- Brinell hardness number, HB, of not more than 180.
Technological features of the material deformability in a cold state — the poor, the rolling of the alloy can be bad, only hot deformation in the temperature range of 850…900°C.
