 1 GB HSn62-1 tin brass Overview 
 Added tin brass, can significantly improve the heat resistance of the alloy, in particular, is to improve the capacity of sea water resistant, so the tin brass naval brass, "said. Tin can integrate into the copper-based solid solution, since the solid solution strengthening effect. With increasing tin content alloys brittle r phase (CuZnSn compounds), plastic deformation is not conducive to alloy tin content of tin brass is generally in the range of 0.5% to 1.5%. Tin brass have HSn90 to-1, of HSn70-1, HSn62-1, HSn60-1. Former alpha alloys with high ductility, cold, heat stress processing. The latter two grades of alloy (α + β) two-phase structure, and often a small amount of r phase, the room temperature ductility is not high, only deformation in the hot state. 
 Its main add the main properties of the chemical element tin as follows: 
 Name: tin; 
 tin formula: SN 
 Molecular weight: 118.710 
 Density: 7.31 (alpha type) 
 Melting point: 231.85 (alpha type) ℃ 
 Boiling Point: 2507 (alpha type) ℃ 
 Characters: white tin (α), gray tin (beta), and brittle tin (gamma type) three allotropic forms body. Common white tin, gray metal. 
 Uses: used in making tin bearing alloy, bronze, etc., and for tinning and system hoses, tin alloy solder, tin housewares products. 
 Preparation or sources: the main mineral raw materials is cassiterite. To remove impurities such as sulfur and arsenic, placed in the reverberatory furnace using carbon reduction and primary processing of tin, heating remelting purification or refining electrolysis system of pure tin. 
 Note: atomic number 50, atomic weight 118.710, the valence of +2, +4. Chemical properties are relatively stable. Almost no reaction at room temperature, and air.

 HSn62-1 commonly known as 62-1 tin brass, also known as naval brass, tin brass company mainly engaged in the production agent is as follows, 
 HSn90-1, HSn70-1, HSn62-1, HSn60-1, C42200, C42250, C43000, C43400 
 Code: H + main (in addition to zinc) + mass fraction of copper + main add the element mass fraction and element symbols + and the other elements of the mass fraction of. 
 Such as: HSn62-1 copper mass fraction of 62%, with main added element tin mass fraction of 1% margin of zinc tin brass. 

 3 the GB HSn62-1 tin brass features 
 The HSn62-1 tin brass containing traces of arsenic, copper and zinc tin ternary system of a single-phase brass, as a Chinese national standard (GB5232-85) classification and arsenic brass. Trace arsenic can inhibit dezincification, to further improve the corrosion resistance of alloy. HSn62-1 has good mechanical properties, the conduit for the production of heat exchanger and exposure to corrosive liquids, in particular, are widely used in the inland heat and power plant production of high strength corrosion resistant heat exchanger condenser. In recent years, studies have shown that traces of boron, nickel and other elements added to the HSn62-1, better able to improve the corrosion resistance of alloy. HSn62-1, stress corrosion cracking tendency, on the cold pipe to eliminate the stress of low temperature annealing. HSn62-1 hot pressing processing easy to crack, we must strictly control the content of impurities. 

 Imports C43000 tin brass scope of 
 of tin brass, copper and zinc alloy base on the tin brass. Tin brass in freshwater and seawater corrosion resistance, generally referred to the Navy brass. Tin brass tin content of 1% tin too much, reduce the plasticity of the alloy. The zinc content in the alloy, is divided into alpha tin brass, tin (α + β) brass. Single-phase tin brass such as 70Cu-29Zn-1Sn, with good mechanical properties, the soft state of the tensile strength of 350MPa, an elongation of 60%, excellent cold working properties and can withstand the hot-rolled and hot extrusion, but not to thermal shock and thermal forging. Widely used in high-strength corrosion of the vessels, heat and power plant condenser. Such alloys stress corrosion cracking tendency and cold pipes must be low-temperature annealing to remove stress. (Α + β) tin brass such as 62Cu-37Zn-1Sn, have good mechanical properties, soft-state tensile strength 380MPa, elongation 40%, can be cold and hot pressure processing, cutting, welding, in the sea has high corrosion resistance, contact parts for ship parts, and seawater. 
 (1): HSn90-1. High corrosion resistance and friction reduction, the approximation of a simple brass H90, its mechanical properties for the production of automobile, tractor elastic casing and other corrosion antifriction parts. 
 (2) of HSn70-1. Containing traces of arsenic, copper and zinc tin ternary system of a single-phase brass, as in the Chinese national standard (GB5232-85) classification and arsenic brass. Trace arsenic can inhibit dezincification, to further improve the corrosion resistance of alloy. HSn70-1 has good mechanical properties, the catheter used to produce heat exchanger and exposure to corrosive liquids, in particular, are widely used in the inland heat and power plant production of high strength corrosion resistant heat exchanger condenser. In recent years, studies have shown that traces of boron, nickel and other elements added to the HSn70-1, better able to improve the corrosion resistance of alloy. HSn70-1, stress corrosion cracking tendency of cold pipes must be carried out to eliminate the stress of low temperature annealing. HSn70-1 hot pressing processing easy to crack, we must strictly control the content of impurities. 
 (3) the HSn62-1. Has good mechanical properties, machinability and weldability, high corrosion resistance in seawater, and can withstand heat, cold, pressure processing in the shipbuilding industry for manufacturing and seawater contact parts. 
 (4)-l HSn60. High corrosion resistance, its performance is similar to HSn62-1, pressure processed into bar and wire used in the shipbuilding industry as a welded structure of the electrode.
