What is Changzhou zinc alloy bearing seat?

Zinc alloy bearing seat is an alloy composed of zinc as the base and other elements. Commonly added alloying elements include aluminum, copper, magnesium, cadmium, lead, titanium, etc. Zinc based alloys have a low melting point, good fluidity, are easy to melt and weld, undergo brazing and plastic processing, and are resistant to corrosion in the atmosphere. Residual waste is easy to recover and remelt; But the creep strength is low, and it is prone to scale changes caused by natural aging. Preparation by melting method, die-casting or pressure processing into materials. According to manufacturing processes, it can be divided into cast zinc based alloys and deformed zinc based alloys.

Comparison with Babbitt alloy

In addition to having obvious cost-effectiveness advantages, it also has higher durability, lower weight, and wider application scale.

Compared to bronze

1. The strength, hardness, and allowable pressure are appropriate to aluminum bronze, widely surpassing tin, lead, etc., and the allowable speed is near. It can fully meet the application conditions of independent anti friction and wear-resistant parts such as bearings.

2. It has a strong affinity for lubricating oil, better self-lubricating properties, and its metallurgical properties (low melting point, difficult to metallurgical combine with steel shafts) make it more resistant to adhesion and outstanding in reducing friction and wear resistance during use.

3. The conflict coefficient is low, the wear is small, and therefore the service life is longer. Under equal usage conditions, the cost of purchasing accessories is generally reduced by more than times that of copper tiles.

4. High thermal conductivity (ZZnAl27Cu2Mgλ=25; ZCuAl0Fe3λ=59), fast heat dissipation, slow and low surface temperature rise, providing better protection against pairing conflicts.

5. Low data density (ZnAl27Cu2Mgρ=5g/cm3), light product weight (same model, same standard weight/3), simpler and more convenient installation and protection.

6. It has high damping characteristics and is resistant to vibration and noise.

Kind reminder: This concludes the article. I believe you have gained some understanding of zinc alloy bearing seats. If you have any other questions, all employees of Changzhou Shihui Transmission Parts Co., Ltd. are welcome to call for consultation.
