Sichuan 5086 aluminum, aluminum row of low-priced wholesale spot, HPb59-2 lead brass square bar manufacturer

5086 aluminum standard: GB / T 4437.1-2000 magnesium alloy also referred to as the anti-rust aluminum-manganese alloy aluminum alloy components because both have increased their intermediate anti-corrosion properties of aluminum alloy 5086 aluminum-manganese alloy represented 3003,3004, 3105, aluminum-magnesium alloy magnesium alloy according to the level of content were 5005 5,252,525,150,505,052 5,754,508,350,565,086 so on. 5086 aluminum Typical uses: for applications that require high corrosion resistance, good weldability and moderate-intensity situations, such as ships, cars and aircraft panels can be welded parts; the need for strict fire of pressure vessels, refrigeration equipment, tower, equipment exploration equipment, transportation equipment, missile parts, armor and so on. 5086 aluminum Supply Status: O, H112, H116, H111, H321, H32, H36, H38 Chemical Composition: Aluminium Al: margin silicon Si: ≤0.40 copper Cu: ≤0.10 magnesium Mg: 3.5 ~ 4.5 Zinc Zn: ≤0.25 Manganese Mn: 0.20 ~ 0.7 Titanium Ti: ≤0.15 chromium Cr: 0.05 ~ 0.25 iron Fe: 0.000 ~ 0.500 Note: Single: ≤0.05; Total: ≤0.15 Mechanical Properties: Tensile strength σb (MPa): ≥240 Conditions yield strength σ0.2 (MPa): ≥95 Elongation δ10 (%): ≥10 Elongation δ5 (%): ≥12 Note: longitudinal pipe temperature mechanical properties Sample Size: All Thickness status: aluminum and aluminum alloy extruded seamless tube (H112 condition) HPb59-2 lead brass Product Name: Chemical composition and characteristics: the main component of Cu 57.5-59.5 Pb2.0-2.8 Zn: balance impurities% Fe≤ 0.5 Ni-- sum of impurities% ≤1.2 characteristic hardness, strength, and lead shot distribution, long-term use does not warp. Widely used lead-lead brass brass CuZn39pb2: nature: on the basis of the copper-zinc alloy, adding lead brass. According to the amount of zinc can be divided into single-phase α lead brass, two-phase (α + β) brass lead. Only single-phase α lead brass cold rolling and hot extrusion, commonly used 63Cu-34Zn-3Pb alloy, the soft state of the tensile strength of 350MPa, elongation of 45%. It has high strength and good cold working properties, has excellent machinability, is mainly used for cutting parts with extremely high on the meter and other mechanical instruments. Two-phase (α + β) can lead brass rolled, hot extruded and cold, typical alloy 59Cu-40Zn-1Pb, at a temperature range of 550 ~ 650 ℃ has superplasticity, high strength and excellent cutting performance, the soft state of tensile strength 420MPa, an elongation of 45%, is the most economical, the most commonly used leaded brass. For the production of thermal coal mine and machining parts, screws, washers, bushings, nuts, base, bearing retainer, etc.
