the super high-manganese materials series was developed, it is achieved that the spare parts of global famous crusher or mill equipments companies (as Germany Aubema, Krupp & Hazemag) are made of China.

bimetal thermal-composite wear-resistance materials (China Patent No. 200810049101) was developed, which we have whole intellectual property of it. We successfully combined two different features of high-hardness materials and high-ductile materials into single part to full work. This part of work degree hardness is HRC62-65, abrasion resistance, impact resistance, excellent overall performance. It is especially used to the hammer and board hammer of large crushers & the lining plate of large ball mill, Remarkable effects particularly when it worked in harsh environment of mining conditions, for many crushing field as limestone, cement clinker, sand stone, coal spoil, basalt etc.
