Bimetal Bearing -720 refers to a type of bearing that utilizes a high-hardness bimetallic strip as its main material. This bimetallic strip is composed of two different metals, typically CuPb24Sn4 and CuPb30, which are combined to create a material that exhibits excellent wear resistance, corrosion resistance, and load-bearing capacity.
CuPb24Sn4, also known as leaded tin bronze, is a copper-based alloy that contains 24% tin and 4% lead. It offers good machinability and wear resistance, making it suitable for use in bearings and other friction-prone applications.
CuPb30, on the other hand, is a high-lead bronze alloy containing 30% lead. This alloy exhibits high hardness and excellent wear resistance, allowing it to withstand heavy loads and frequent friction.
When combined, these two alloys create a bimetallic strip that offers the best of both worlds: the machinability and corrosion resistance of CuPb24Sn4, and the high hardness and wear resistance of CuPb30. This material is then used to create bushings, which are inserted into bearings to provide a smooth, durable surface for rotating shafts or other moving parts.
Overall, Bimetal Bearing -720 High Hardness Bimetallic Strip Metals Plates CuPb24Sn4 & CuPb30 Bushing Material offers a reliable and long-lasting solution for a wide range of bearing applications.

This is a bimetal bearing material in which bronze alloy comprise a two layer structure with a steel backing. This structure, whose mechanical strength is high, can be used under lubricated conditions and high-speed/high-load operation. It can be made from a variety of different materials, depending on the application, use conditions and lubrication.
Bimetal series materials, also known as bimetallic materials or steel backed strips, are made of low carbon steel or steel coil as the base material, and the surface is sintered with bronze alloy steel and bronze alloy products. Different bronze alloy materials are suitable for different working conditions. The surface copper alloy grades can be divided into high lead series, lead series and lead-free series.

Marketing network refers to the network formed by enterprises and
other enterprises with which they have established strong business
relations of mutual trust.In the marketing network, enterprises can
find strategic partners and associate with them to obtain a wider
and more effective geographical possession.Such networks go beyond
the mere concept of a "marketing channel".With the aid of the
network, the enterprise may be on the market with new products at
the same time around the world, and to reduce due to the time lag
of products into the market by aggressive imitator take market
risk, marketing management is also increasingly by the pursuit of
individual trading profit maximization in the past, to pursue the
optimal mutually beneficial relationship with each other.
