Advantages of GNEE A7075 aluminum rod material in the industrial market
7075 aluminum rod is specifically refined to have a faultless surface free of sand holes, trachoma, horizontal lines, air bubbles, and impurity cracks.
Pre-stretching (T651) relieves internal stress, which prevents warping and cracking.
To ensure accurate tolerances, all products correspond to ASTM B211 and AMS requirements.
Consistent chemical composition reduces processing concerns such as "sticky knife."
Heat treatment ensures homogeneous strength and hardness in goods under 300mm.
Computer-controlled production ensures consistency in quality across batches.
Dyeing creates a shiny, defect-free surface with a uniform finish.
Exceptional corrosion resistance, even after extended contact with diverse media.
Capable of withstanding temperatures up to 400°C without distortion.
Bends 180 degrees without cracking, demonstrating its incredible flexibility.

7075 aluminum rod packing
Packed in export wooden boxes or wooden pallets, fumigated wooden pallets, and provided with fumigation certificates.
7075 aluminum bar weight
7075 aluminium alloy has a density of 2.85 g/cm³..
To calculate the weight of an aluminum round rod, use the formula πR²*hx0.0000027 (3.1415*the square of the radius of the aluminum rod*the length of the aluminum rod*density, where the radius length is measured in millimeters).
The weight of the aluminum square rod is calculated as side A*side B*0.0027*h (side length*side length*density*aluminum rod length), using the unit of mm.
7075 Aluminum Rod Price
7075 aluminum rod pricing = (LME ingot price + processing cost) x weight + packaging fee + transportation fee.
Please contact GNEE Aluminum to inquire about the price and processing charge per ton for the specified type of aluminum square rod. The processing fees for 7075 aluminum rods of various sizes vary greatly, and we will offer you with the most competitive quote.
