Bronze bar

It is possible that the horseshoes of legendary centaurs and pegasi were forged from a bronze bar.

Relevance

Bronze has served man faithfully since ancient times. The list of bronze's "specializations" is far from complete: artistic casting, weapons, construction and, since the middle of the 19th century, electrical engineering. This technologically advanced and inexpensive alloy is still successfully used in many industries. It can be easily rolled, cut, brazed with any solder except aluminum bronze, and easily welded. Bronze bars alloyed with nickel and beryllium are particularly tough. It is known not only for its strength and elasticity, (which can be further improved by additional heat treatment), but also for its corrosion resistance and good weldability.

Tin bronze is one of the first alloys mastered by man. It is characterized by corrosion resistance that surpasses many grades of stainless steel in comparison. Tin bronze is quite malleable, forging and strong, has excellent electrical and thermal conductivity Technological its technology is also far superior to stainless alloys. It can be easily rolled, cut, soldered with any solder, and easily welded. It is relevant in many modern industries.

Tin-free bronze rod does not contain in its composition the scarce tin. By its anti-corrosive, technological and mechanical properties it is often superior to the tin bronze bar. Tin-free bronzes can be alloyed with beryllium, aluminum and manganese depending on the technological purposes. Tin-free bronzes comply with GOST 18 175-78. This standard applies to tin-free bronzes of deformable grades designed for the production of billets.

Production

GOST 1628-78 regulates the production of tin-free bronze bars, GOST 6511-60 - tin-zinc bronze bars, GOST 10 025-78 - tin-phosphorus bronze bars. Output of beryllium bronze bars is stipulated by GOST 15 835-70, while BrX1 chrome bronze bars are specified by TU 48-21-408-86. Standardization of chemical composition: bar, which is processed by pressure: GOST 18 175-78 - for tin-free alloys, GOST 5017-74 - for the tin. High-quality bronze bar has no stratifications, voids, non-metallic inclusions. On the surface

Cast bronze bar is produced by horizontal casting in the form of round cross-section bars.

Classification

By production method By precision manufacturing By state of material: By sectional shape: By length.

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

D - drawn (cold-deformed).

B - high,

P - high;

H - normal.

P - semi-hard;

M - soft;

T - hard;

O - extra hard.

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

МD - measured length; ND - short length; КD - divisible length;

BT - in coils.

Special conditions: MP - measured bronze bar of increased accuracy in length; AB - bar for machining on automatic machines.

Application

Due to corrosion resistance and accessibility to any type of machining, bronze bar serves as a blank for nuts, bolts, bushings, spindles, shafts, valves, parts of water and gas systems, assemblies of units and structural elements, which are widely used in shipbuilding, construction, electrical engineering and instrumentation.

Price

The price of bronze in the region is determined by the price of copper, the state of the country's economy, proximity to copper and tin ore deposits and processing centers. Copper price, in turn, is an indirect indicator of the stability of the country's economy - electronics, engineering and energy, where copper is used as a raw material. Copper price also reflects the dynamics of development of production sectors. How much bronze is worth is determined by the stock exchanges. But when considering this question more privately, one should take into account such indicators as the availability of natural resources in the region and the development of the mining industry. Many people who want to sell scrap bronze are interested in the price per 1 kg. It is not the same everywhere. Ubiquitous access to the Internet makes it easier to find the best option, it is possible to compare prices, consider favorable offers and generally assess the situation with pricing and its dynamics.
