      1. The strength, hardness, and allowable pressure are equivalent to aluminum bronze, widely exceeding tin, lead, etc., and the allowable speed is similar. It can fully meet the usage conditions of independent anti friction and wear-resistant parts such as bearing shells.

      Advantages of using zinc alloy to make bearings with seats

      Compared to Babbitt alloy

      In addition to having significant cost-effectiveness 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 equivalent to aluminum bronze, widely exceeding tin, lead, etc., and the allowable speed is similar. It can fully meet the usage conditions of independent anti friction and wear-resistant parts such as bearing shells.

      2. With a strong affinity for lubricating oil and better self-lubrication, coupled with 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 therefore longer service life. Under the same usage conditions, it is generally more than twice that of copper tiles, thereby reducing the procurement cost of accessories.

      4. High thermal conductivity (ZZnAl27Cu2Mg) λ= 125; ZCuAl10Fe3 λ= 59), fast heat dissipation, slow and low surface temperature rise, providing better protection against paired friction.

      5. Low material density (ZZnAl27Cu2Mg ρ= 5g/cm3), with a lightweight product (1/3 lighter in weight for the same model and specification), making installation and maintenance easier and more convenient.

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