October 26, ” environmental protection type hard tin alloy layer diesel engine axle bush ” finished by Hubei Anda , great prosperous completion of Hubei one ” The accurate bearing bushing of high performance uses one pair of metal materials of unleaded phosphorus bronze ” Two scientific research projects, the provincial expert’s technical appraisement organized through the municipal scientific and technological office. The expert panel thinks unanimously, two items of product technology reach the international most advanced level, propose accelerating employing and popularizing.

It is reported, environmental protection type hard tin alloy layer diesel engine axle bush, it is factory formula and corresponding craft research and wear-resisting copper tin axle bush of low lead become which adopt environmental protection type hard tin alloy layer diesel engine axle bush. The expert thinks, this product resists high fatigue strength, the wearability exceeds three yuan alloy axle bush of tradition notably, corrosion-resistant performance fits trade’s requirement, can be used in famous brand car engines such as wide vapour Toyota, east wind Citroen, Yuchai, tin firewood, Wei firewood, east wind Commings,etc. extensively.

High performance accurate bearing bushing uses one pair of metal materials of unleaded phosphorus bronze, adopt a pair of metal material wear-resisting layer of prescription and relevant production technology to study. The expert does not think the new phosphorus bronze bearing alloy used for in this product include lead,etc. and harmful to the metal, solve the issue on environmental protection that the leaded copper alloy bearing brings, meet the instructions for use of engine of the above discharge standard of Europe.

It is reported, two companies are new high-tech enterprises, lie in the open north industrialized country of Xin County.
