Babbitt alloys有色金属合金，巴比特合金【沃昌牌】

Babbitt metal (inc** tin-based bearing alloy and lead-based bearing alloys) is the most well-known bearing materials, invented by the Americans Babbitt so named because of its white, also known as white alloy of tin with a reduction Mott ChibaS Chiba"s alloy and lead alloy is uniquely suited to rotation axis relative to the low hardness of materials, as compared with other bearing materials, has better adaptability and pressed into nature, widely used in large marine diesel engines, turbines, AC power generationmachines, and other mining machinery and large rotating machinery.

Babbitt alloy composition
Babbit the main ingredient is tin, lead, **mony, copper.Which **mony and copper, to improve the alloy strength and hardness.Babbitt can be simply divided into three types: high-tin alloy, high-lead alloys and master alloys (alloy of tin and lead are an important ratio).In all of these alloys, the **mony and copper are as important alloying elements and hardening elements, and its structure is hard, diffuse soft matrix composed of intermetallic compounds.

Babbitt Category
According to national standards, babbitt can be divided into tin-based alloys and two kinds of lead-based alloys.Lead-based alloy strength and hardness than the tin-based alloy is low, the corrosion resistance is also poor.Therefore, in the use babbitt time, usually use tin-based alloys, their usual brands are ZChSnSb11-6, ZChSnSb8-4, ZChSnSb8-8 and so on.Lead-based bearing alloy hardness, strength and toughness than the tin-based bearing alloy is low, often doing low-speed, low-load bearing alloy used.Although the performance of lead-based alloys without tin-based alloys is good, but there are many customers still choose to use, because it is more economical to use, their usual brands are ZChPbSb16-16-2, ZChPbSb1-16-1 and so on.
