Bronze rods BrAZh are distinguished by their mechanical strength and increased corrosion resistance, therefore, bronze blanks are made from them. The technology for the production of billets can be cold-deformed, drawn, hot-deformed or rolled (pressed). Hot rolled bars are made of tin-free bronze.
Based on the physical characteristics of hardness, bronze rods are soft, semi-hard and hard. In cross-sectional shape, the rods are round (bronze circle), square (bronze square), hexagonal (bronze hexagon). Prices for BrAZh rods depend on the degree of accuracy with which they are manufactured. Based on this characteristic, rods are classified into products of normal, increased or high accuracy.
With any degree of accuracy, the structure of the bar should be free of voids, alloy delamination and non-metallic inclusions. Differences in accuracy only indicate whether there are minor defects on the surface of the bar.
Composition of bronze bars
BraZh is an alloy of bronze with aluminum. The numbers indicate the ratio of the content of the ingredients. Among the advantages of the BrAZh 9-4 rod, the following characteristics are noted: heat resistance, resistance to moisture, low relative elongation. Iron is needed for the alloy to reduce grain size, aluminum to improve resistance.
Due to the presence of good mechanical properties, BrAZh is used in industry, and due to its increased resistance to corrosion, rods are used in shipbuilding. Bronze rods are sold in various sizes, including custom made. More information can be obtained on the specialized site metal-komplekt.ru .
The cross section of the bronze rods can be a circle or a hexagon. The chemical composition of extruded and drawn rods must comply with GOST 18175. There should be no damage or burrs on the surface of the rods. For the manufacture of these products are guided by GOST 10025, in accordance with various technical conditions. In the production of cast bronze wheels, the method of horizontal casting is used.
The delivery of rods is carried out in bundles, which are tied with tape or wire, stacked slings. The classification of bronze rods is carried out according to the type of material, according to the state of the alloy, according to the accuracy of production, according to the length.
