Bronze circle

The essence of advertising is not so much the advertisers' desire to seduce as our desire to be seduced. Dan Burstyn, American writer.

Advantages

Bronze circle has an exceptional corrosion resistance that surpasses many grades of stainless steel in comparison. It is quite ductile, malleable and tensile strong, and has excellent electrical and thermal conductivity Technologically it is also far superior to stainless alloys. It can be easily rolled, cut, brazed with any solder except aluminum bronze, and easily welded. Bronze circle is relevant in many modern industries. A particularly strong circle alloyed with nickel and beryllium. It is known not only for strength and resilience, (which can be further improved by an additional heat treatment), but also corrosion resistance and good weldability.

Production

Bronze circle produce according to the following GOST: 5222-72, 5221-77, 15 834-77. For the production of usually used alloys alloyed with zinc BrOC4-3; BrKhTsrK; manganese BrAMTs9-2; BrAJHNMTs 8,5-4-5 -.1,5; BrKMC3-1; BrNHK 2,5-0,7-0,6; BrB2,5; BrB2 silicon, BrOF10-1 and BrOF7-0,2 tin-phosphorus alloys. Production of a circle for electrodes contact welding machines of chromium bronze BrX1 is regulated by TU 48-21-408-86. In a drawn a circle, grade BrKMts3-1 before machining pressure to remove internal stress.

Quality standardization

The composition of the circle of tin-free wrought alloys that are processed by pressure normalize GOST 18 175-78, tin - GOST 5017-74. Preparation and sampling to determine the chemical composition of bronze alloys is carried out according to GOST 24 231-80. The finished circle should be homogeneous, with no extraneous inclusions or stratification. Traces of broaching, slight irregularities within the limits stipulated by GOST are allowed.

P - pressed (hot-deformed) - usually on the basis of tin-free bronze; D - rolled;

D - drawn (cold-deformed).

: B - high, P - elevated; N - normal.

P - semi-hard; M - soft; T - hard;

RL - circle; SHG - hexagon; SQ - square.

MD - longitudinal length; ND - shortitudinal length; QD - multiple length;

BT - in coils.

Special conditions: MP - dimensional circles of increased accuracy in length; AB - circles for machining on automatic machines.

Application

Due to corrosion resistance, and the availability of any type of machining, the bronze circle serves as blanks for nuts, bolts, bushings, gears, spindles, shafts, valves, parts of water and gas systems, nodes and structural elements, which are widely used in shipbuilding, construction, electrical engineering and instrumentation.
