The new aluminum base sliding bearing alloy and its bearing products

A new type of aluminum base sliding bearing alloy and its 2018 - bearing products 11 - 16' Results summary 】 The industrial pure aluminum as the main raw material, adding several kinds of alloying elements, smelting, casting blank sliding bearing, the mechanical processing and assembly after use. It is mainly used for replace ZQSn6 - 6 - 3, ZCuSn5Pb5Zn5, tin bronze bearing and all kinds of double metal bearing, shaft sleeve, etc. The results obtained in 2003 in sichuan province science and technology progress third prize. Tensile strength & sigma; B180 ~ 210 mpa, 68 ~ 76 HBS hardness, elongation & delta; 4% ~ 8%, the mechanical properties of tin bronze and its friction coefficient (& mu; 0. (004) is far lower than the tin bronze, density & rho; 2. 9 g/cm3) was only about a third of tin bronze. Melting temperature of copper alloy is much lower, no environmental pollution. 【 The market application and investment benefit analysis 】 New aluminum base sliding bearing alloy and bearing products, has been in the automotive oil pump and air compressor machine, forging machine tool successfully batch applications for several years. Replace the tin bronze manufacturing integral sliding bearing (bearings, bushings, etc. ), reduce the cost of materials more than two-thirds; Used to replace the double metal sleeve, drop costs about 1/2. The products are widely used in all kinds of dump truck, hydraulic machinery, forging machinery, engineering machinery, grain and oil machinery, mining machinery, petroleum machinery, chemical machinery, plastics machinery and all kinds of machine tools and other equipment. Mass production of smelting equipment and tools of investment in 600000 yuan, only about ten workers can form the annual output value of nearly ten million yuan, benefit is very considerable.
