Valve seal tin-based babbitt alloy tin-bismuth alloy sealing block

Henan Huachuang Metal Materials Trading Co., Ltd. produces and sells Babbitt alloy, tin-based alloy, lead-based alloy, bearing alloy, tin-based Babbitt alloy, and Babbitt alloy bearing bushes. The main products include tin-based alloys (4-4, melting point 225, hardness 28.6, suitable for various turbines, internal combustion engines, and high-speed bearing bushes; 8-4, melting point 238, hardness 34.3, high hardness, high load pressure, more suitable for large machinery bearings and bushes; 11-6, melting point 240, hardness 30, suitable for high-speed steam engines above 2000 horsepower, and 500 horsepower turbines, turbo compressors, turbo pumps, and fast internal combustion engines). Tin-based Babbitt alloy offers advantages such as high temperature resistance, wear resistance, corrosion resistance, compression resistance, and shock resistance. Tin is the primary element, along with copper, antimony, and lead. The structure of tin-based alloys consists of a soft matrix and hard particles. When sliding bearings are in operation, the hard particles in the matrix support the bearing and withstand friction, while the soft matrix ensures good compatibility between the bearing and the journal. Therefore, tin-based Babbitt alloy is ideal for casting mechanical bearing bushes, bushings, and liners. It is mainly used in cement ball mills, compressors, rolling mills, hydraulic turbines, turbines, compressors, turbo pumps, fast internal combustion engines, ball mills, mineral processing equipment bearings, metal ore mills, elevators, slings, wire rope fastenings, and other large machinery bearing bushes, bushings, and liners. It is also used as a filling product for mechanical seals, sling fastenings, machine tool alloy sliding pads, grinding machine support cast pads, sliders, etc. Quality standards: Complies with GB/T1174-1992 casting alloy standards; Characteristics: Block form with silvery-white metallic luster; Thrust bearing bushes differ from other sliding bearing bushes. In thrust bearings, they are used to fix the transmission shaft and bear axial forces from the transmission shaft (i.e., the force direction is consistent with the axial direction), providing a thrust-limiting function. The part of the thrust bearing that supports the bearing is called the journal, and the component matched with the journal is called the bearing bush. Bearings operating under sliding friction. Under liquid lubrication conditions, the sliding surfaces are separated by lubricating oil without direct contact, significantly reducing friction loss and surface wear, with a long service life. They are commonly used in high-speed, heavy-load components. The oil film also has certain vibration absorption capabilities, making sliding bearings operate smoothly, reliably, and noiselessly. Therefore, customers prefer tin-based Babbitt alloy.
