Introduction to Zinc Alloy Bearings

An alloy consisting of zinc as a base and other elements. The commonly added alloying elements include aluminum, copper, magnesium, cadmium, lead, titanium, and so on. Zinc based alloys have a low melting point, good fluidity, and are easy to melt, solder, and plastic process. They are corrosion resistant in the atmosphere, and are easy to recover and remelt; However, due to its low creep strength, it is prone to dimensional changes caused by natural aging. Prepared by melting method, die casting or pressure processing. According to the manufacturing process, it can be divided into cast zinc based alloys and deformed zinc based alloys.

Compared to babbitt alloy

In addition to significant cost performance advantages, it also has higher strength and toughness, lower proportion, and wider application range.

Compared to bronze

1. The strength, hardness, and allowable pressure are comparable to aluminum bronze, widely exceeding tin, lead, and the allowable speed is similar. It can fully meet the service conditions of independent antifriction and wear-resistant parts such as bearing pads.

2. Due to its strong affinity for lubricating oil and better self-lubrication, as well as its metallurgical properties (low melting point, difficult to metallurgical bond with steel shafts), it has strong adhesion resistance and more prominent friction and wear resistance characteristics in use.

3. Low friction coefficient, low wear, and longer service life. Under the same usage conditions, it is generally more than times the size of copper tiles, thereby reducing the procurement cost of accessories.

4. High thermal conductivity (ZZnAl27Cu2Mg=25; ZCuAl0Fe3=59), fast heat dissipation, slow and low surface temperature rise, providing better protection against pairing friction.

5. The material density is low (ZnAl27Cu2Mgρ=5g/cm3), and the product quality is light (the same model and specification are light/3), making installation and maintenance easier and more convenient.

6. With high damping characteristics, it can reduce vibration and resist noise.
