Metallography & Characteristics

Note: Where the product can also choose a different base materials according to different conditions, such as: bronze substrate (HYB-11), a stainless steel substrate (HYB-60), and lead-free (HYB-13) and other formulations.

Application characteristics 1. The mixture of PTFE and lead can form a good transfer film to protect the grinding shaft during movement.
2. The sintered layer and the copper substrate have good thermal conductivity and can quickly transfer heat generated during operation.
3, copper has self-lubricating properties, can be used for long-term operation and can not be shut down for maintenance.
4. The base copper has good corrosion resistance and can be used in weak acid and strong alkali occasions.
5, has a good carrying capacity.
6. The products have been widely used in metallurgical steel industry, high temperature furnace steel ring parts, cement grouting pumps, screw conveyors, port machinery and ship machinery.
7. The steel sleeve can be combined externally; or the flange can be made to achieve the effect of simultaneously using the inner hole and the end surface.
