Can aluminum bronze be replaced by tin bronze plate?
As an elastic alloy, tin bronze plate refers to a copper-tin alloy containing Sn≤6.5%, usually still containing P, Zn and other alloy elements. If it also contains P, it is called phosphor-tin bronze, which has high elastic limit, elastic modulus, good resistance Wear and corrosion resistance, suitable for the manufacture of various elastic components. The aluminum content of aluminum bronze generally does not exceed 11.5%, and sometimes an appropriate amount of iron, nickel, manganese and other elements are added to further improve the performance. Aluminum bronze can be strengthened by heat treatment, its strength is higher than that of tin bronze plate, and its resistance to high temperature oxidation is also better. It is used for high-strength screws, nuts, copper sleeves, sealing rings, etc., and wear-resistant parts. The most prominent feature is its good wear resistance. For aluminum bronze containing iron and manganese elements, it has high strength and wear resistance. After quenching and tempering, the hardness can be increased, and it has good high temperature corrosion resistance and oxidation resistance. Corrosion resistance in the atmosphere, fresh water and sea water Very good, the machinability is acceptable, it can be welded and not easily brazed, and the pressure processing is good in the hot state. Both tin bronze plate and aluminum bronze are wear-resistant materials.
Since the steel indenter is deformed during measurement, the sand type metal type. The size and load of the indenter remain unchanged, HBS, especially when the measurement material is hard, and the relationship between HBW: HB is the Brinell hardness value: ZCuSn5Pb5Zn5; the Brinell hardness value in the new standard clearly specifies the indenter during measurement : Tensile strength σb (MPa): HBW refers to a cemented carbide indenter: 590HB. Due to the deformation of the steel indenter during measurement, the new standard reduces the loopholes in this regard: ≥90; elongation δ5 (%): ≥13. Note: HWS refers to a steel indenter, so here is the first distinction, especially when measuring harder materials, the new standard reduces loopholes in this regard.
