Detailed Product Description: | ● H59-1 Heat Specifications: thermal processing temperature of 640 ~ 780 ℃; annealing temperature of 600 ~ 650 ℃; eliminate the stress of low temperature annealing temperature 285 ℃. ● H59-1, mechanical properties: tensile strength ≥ 420, elongation ≥ 10, elongation ≥ 12, Note: The vertical bar tensile properties at room temperature, the sample size: the diameter or edge distance of 5 to 20 Chemical composition ● H59-1: H59-1 copper (Cu) 58.0 ~ 60.0, H59-1 zinc (Zn) balance, H59-1 lead (Pb) 0.8 ~ 1.9, H59-1 phosphorus (P) ≤ 0.02, aluminum (Al) ≤ 0.2, iron (Fe) ≤ 0.5, H59-1 containing antimony (Sb) ≤ 0.01, bismuth (Bi) ≤ 0.003, (Note) ≤ 1.0 (impurity) ● H59-1 Features and Range: is the application of a wider lead brass, good machinability, good mechanical properties, can withstand cold, hot pressure processing, easy fiber welding and welding of corrosion in general have good stability, but corrosion cracking tendency Lead Brass meaning almost no solid solution of lead binary alloy of copper and zinc, in the free state in isolation distribution in solid solution. Lead particles have excellent lubricity and antifriction properties, its high surface precision machined parts. To evaluate the machinability of a metal material, usually brass HPb63-3 cutting can lead to 100%, and the metal can be evaluated cutting HPb63-3 corresponds to a few percent. Cutting brass with lead levels can be increased. Leaded brass parts exist in the use of lead leaching problem, causing environmental pollution. Therefore, studies are generally launched environmentally friendly alloy, bismuth and antimony main choice of two factors, but due to resource constraints, replace leaded brass goal difficult to achieve. Lead Brass (commonly known as cutting brass): Lead is virtually insoluble in the brass, the state was free particle distribution in the grain boundary. In the copper-zinc alloy, based on adding lead brass. According to the amount of zinc can be divided into single-phase α leaded brass, two-phase (α + β) lead brass. Only single-phase α leaded brass cold-rolled and hot extrusion, commonly used 63Cu-34Zn-3Pb alloy, the tensile strength of the soft state 350MPa, elongation of 45%. Having high strength and excellent cold workability, excellent machinability, high machinability main requirements for the instruments and other parts of mechanical instruments. Two-phase (α + β) can lead brass rolled, hot extruded and cold, typical alloys 59Cu-40Zn-1Pb, at a temperature range of 550 ~ 650 ℃ has superplasticity, high strength and excellent cutting properties, tensile strength of the soft state 420MPa, elongation of 45%, is the most economical, the most commonly used lead-brass. For the production of thermal coal mine and machining parts, screws, washers, bushings, nuts, base, bearing retainer and so on. Brass composition, performance and application Brass is an alloy of copper and zinc. The simplest brass copper - zinc binary alloy, called simple brass or ordinary brass, changing the content of zinc in brass can get different mechanical properties of brass. The higher levels of zinc in brass, its intensity is higher, lower plasticity. The brass industry used does not exceed 45% of the high zinc content will be brittle, the alloy performance deterioration. The ability of resistance to seawater and brass plus 1% tin can significantly improve the marine atmospheric corrosion of brass, so called "Navy brass." Tin can improve the cutting performance of brass. Leaded brass that we usually refer to easy to cut GB copper. The main purpose is to increase the lead to improve machinability and improved abrasion resistance, impact of lead on the strength of brass. Lead is also a sculpture of copper brass. Most brass has good color, processing, scalability, ease of plating or coating. Common brands are: H65 H62 H59 Hpb63-3, Hpb62-3, Hpb60-2, Hpb59-3, Hpb59-1, Hpb58-3, etc. Typical Chemical Composition% Cu Fe Pb Ni Zn sum,,,, impurity H68 [C2620 ] 67.0-70.0 margin 0.1 0.03 0.5 0.3 H65 [C2680] 63.5-68.0 0.1 0.03 0.5 margin 0.3 H62 60.5-63.5 0.15 0.08 0.5 margin 0.5 H59 57.0-60.0 0.3 0.5 0.5 Balance 1 HPb59-1 lead brass 57.0 -60.0 0.5 0.8-1.9 1 margin a product name similar to the Chinese standard grades of foreign brands Size (mm) Features and uses international standards USA Japan UK Germany Plate: Thickness 0.5-3.0mm Width: 610 (maximum) length 2500 (maximum) with : Excellent thickness 0.15-3.00mm width 610 (maximum) scalability and deep-drawing performance, good plating. |
