Bronze circles BrAMts 9-2
Bronze Circle (bar) is a type of bronze rolled. BrAMts 9 - 2 - is Tinless, copper alloy, processed by pressure, the main alloying element which acts as aluminum. Its production is carried out or go Hot-pressed and cold-pull techniques. The chemical composition and the brand tinless bronze wrought alloys, which include BrAMts 9 - 2 are determined by GOST 18175 and GOST 1628.
Chemical composition:
- Copper - base

Aluminum bronze BrAMts 9 - 2 has a high resistance at alternating load.
Followed BrAMts 9 -2 are used for the production of shafts, propellers, gears, bushes, parts for hydraulic installations for the manufacture of parts of vessels in the chemical industry. In the form of semi-finished products of this brand are produced bronze circles, rods, wire. The wire is used for welding of copper, brass, copper - nickel alloy with aluminum-manganese bronze, for manual and mechanized welding on steel. Welding wire is manufactured in twisted bay or wound onto a reel. Followed BrAMts 9 - 2 are available cross-section of 16 mm - 160 mm, length - 3000 mm. Cold-circles are rare, available only on request.
