Bronze-clad iron powder is mainly used to manufacture oil-impregnated bearings, especially for the manufacture of miniature oil-impregnated bearings, pressed copper parts and structural parts. Bronze-clad iron powder is a new product that replaces the traditional 6-6-3 tin bronze powder.
Compared with products made of 6-6-3 tin bronze powder, oil-bearing bearings and structural parts made of bronze-clad iron powder have low production costs (only one third of the price of 6-6-3 tin bronze powder) High purity, good lubricity, corrosion resistance, good product color (the same color as 6-6-3 tin bronze powder), it is an ideal material to replace tin bronze powder.
Bronze-clad iron powder plays an important role in the diamond tool manufacturing industry, and its application is becoming more and more common. At present, in the manufacture of diamond tools, iron powder and copper powder are used as a metal bonding agent, and there is a powder mixing process and Segregation is prone to occur during use. In the process of sintering and hot pressing, the alloying degree of iron powder and copper powder is low and it is easy to produce cementite. The diamond surface is graphitized, and the strength is greatly reduced, which ultimately reduces the service life of diamond tools. When the bronze-clad iron powder is used to replace the mixed iron-copper powder, segregation will not occur, thereby increasing the strength of the diamond and improving the service life.
Bronze-clad iron powder is mainly used to manufacture oil-impregnated bearings, especially for the manufacture of miniature oil-impregnated bearings, pressed copper parts and structural parts. Bronze-clad iron powder is a new product that replaces the traditional 6-6-3 tin bronze powder.
In addition to the low price of the product, the composite powder series products have a high degree of alloying and uniform composition, which overcomes the two major shortcomings of mechanically mixed powders that are prone to chemical composition and structure segregation, and provides a strong guarantee for the stability of the performance of powder metallurgy products. . In addition, the product composition can be adjusted within a certain range, which can meet the requirements of customers for producing products with different properties.
Copper-clad iron powder is a new type of composite powder with iron powder as the core and a layer of pure copper uniformly plated on the surface. The copper-clad iron powder developed and produced by our company has the characteristics of complete coating, bright color and excellent oxidation resistance, according to its performance characteristics.
Because the outer layer of iron powder is plated with a dense pure copper layer, it can improve the heat transfer channel of the friction material, increase the thermal conductivity of the friction material, and thereby improve the thermal conductivity and temperature conductivity of the friction material. At the same time, due to the increase in the degree of alloying between the metal powders during the sintering process, the mechanical properties of the friction material can be improved.
