The LD10 aluminum rod belongs to the aluminum-magnesium alloy plate, which is widely used, especially the aluminum alloy plate that cannot be used without the construction industry, and is also the most promising aluminum-gold plate.
LD10 aluminum rod is often used in the manufacture of aircraft and automobile fuel tanks, oil pipes, as well as vehicles, ships sheet metal parts, instruments, street lamp bracket and rivets, hardware products, electrical shell, etc.
3. Chemical composition of LD10 aluminum rod: aluminum Al: allowance; Si Si: 0.25; Copper Cu: 0.10; Magnesium Mg: 2.2 ~ 2.8; Zinc and zinc: 0.10; Manganese Mn: 0.10; Chromium Cr: 0.15 ~ 0.35; Iron Fe: 0.4 0.
Mechanical performance of LD10 aluminium bar: yield strength sigma 0.2 (MPa)≥65 modulus of elasticity :E 69.3~70.7Gpa annealing temperature :345℃
1. No cracks, corrosion spots and saltpeter marks are allowed on the surface.
2. Peeling, bubble, surface roughness and local mechanical damage shall be allowed on the surface with a depth not exceeding 8% of the nominal wall thickness of the part where the defect is located, but the maximum depth of the defect shall not exceed 0.5mm, and the total defect area shall not exceed 5% of the total plate area.
3. Allow the supplier to shine along the profile longitudinally until the surface is smooth.
4. Other requirements: formulated by the demander and the supplier.
LD10 aluminum rod can be welded with LD10 electrode, after welding, it can meet the mechanical properties of LD10 aluminum rod. Fe: 0.40; Cu: 0.10; Mn: 0.05-0.20; Mg: 4.5-5.6; Cu: 0.02-0.20; Zinc: 0.10-0.20; Ti: 0.06-0.20; Al: allowance; LD10 contains a higher amount of magnesium.
Seven, LD10 aluminium rods series and 1060 series aluminum plate hardness: the difference between the tensile strength of LD10 aluminium rods for between 110-130, while the tensile strength of 5056 series, 210-230 or 5056 high hardness will be 1060 reply 100% elongation, elongation is 5%, of the 1060 series and 5052 series of elongation reached between 12-16%, can also think so, in the 5056 series is harder than 1060 100% of cases, elongation is improved by about 200%. Chemical properties :1060 is pure aluminum plate,5056 is alloy aluminum plate, the corrosion resistance of 5056 is better under special circumstances.
