Zinc-based alloy Description zinc-based alloy parts with high mechanical properties, excellent tribological properties, wear resistance, non-sparking and non-magnetic characteristics, can replace more expensive (tin, aluminum) and bronze (lead) Brass and other copper alloys and other manufacturing worm Babbit, bushings, nuts, sliders, guides, bushings and other wear-resistant anti-friction parts. Because zinc-based alloy with low prices of raw materials, energy consumption melting, melting pollution, methods of forming and machining wide adaptability and good range of benefits, and thus the use of zinc-based anti-friction wear-resistant alloy parts has huge economic benefits and social benefits. In the zinc-based alloy, ZA27 strength, ductility, toughness and fatigue strength is the highest. Zinc alloy eutectic compared tensile strength increased by about 50%, to improve the creep strength at room temperature 3 to 4 times, under sustained stress conditions, the actual operating temperature of the zinc alloy to widen the range of 150 ℃. Compared with the 6-6-3 bronze, ZA27 higher strength alloys have lower friction coefficient under dry friction and lubrication conditions, a better carrying capacity, lower friction and a wider temperature liquid lubrication characteristics; almost all available ZA27 alloy instead of using 6-6-3 alloy all occasions. Compared with copper alloys, zinc-based alloy melting point lower. Due to the excellent liquidity zinc-based alloys, zinc-based alloy and therefore only suitable for sand casting, but also for casting, shell casting, metal casting, graphite permanent mold casting, plaster casting, centrifugal casting, continuous casting and squeeze casting . Because the density of ZA27 alloy is only two-thirds of the copper alloy, and its price is about half of the copper alloy. Picture Product Description high strength wear-resistant zinc-based alloy bushings, custom processing of various zinc alloy cover, replace copper sleeve, rough price of 37 yuan per kilogram, definitely wear durability, replace the original 9-4,10- 1, 6-6-3 and other copper alloys. Large favorable price, sold throughout the country. Zinc Alloy own characteristics ◆ antifriction good, hit no spark, can be used in applications requiring high fire safety; ◆ good shock absorption, low noise at work; ◆ low thermal conductivity, less prone to sticking together and wear; ◆ light weight, reducing the mechanical weight; ◆ easy cutting; ◆ corrosion light; ◆ work surface with storage lubricating effect, teach full time job film; ◆ wear-resistant alloy cast zinc base conditions; 1, promote the use of temperature: (1) MZZnAL12-1.8 120 degrees or less (2) MZZnAL27-2.6 150 degrees 2, with the surface speed (linear velocity) V <7.1m / slc 3, bearing pressure P <300T / m 4, not with the use of acid alkaline solution in direct contact with the zinc-based alloy contrast performance compared with babbitt addition to having a significant cost advantage, but also has a higher strength and toughness, lower specific gravity and a wider range of applications such characteristics. Compared with the bronze one, strength, hardness and allowable pressure and aluminum bronze fairly extensive than tin, lead and bronze, the allowable speed similar. Fully able to meet independent friction and wear parts demand conditions such as Bush. 2, a strong affinity for lubricants, better self-lubricating, coupled with its metallurgical characteristics (low melting point, is not easy to take place in conjunction with steel shafts metallurgy), the use of anti-adhesion resistance, friction and wear properties more prominent. 3, low coefficient of friction, wear, thus longer life. Under the same conditions, usually more than one times that of copper, thus reducing procurement costs accessories. 4, large thermal conductivity, heat quickly, slow and low temperature grinding, friction pairing better protection. 5, the low density of the material, light quality, installation, maintenance easier and convenient. 6, with a high damping characteristics, vibration noise immunity.
