7050 aluminum bar is a commonly used aluminum rod material with high strength and hardness, and is widely used in various industrial fields, such as construction, automobiles, aerospace, etc.
7050 aluminum bars and 7075 aluminum rods have similarities and differences in many aspects. The following is a detailed comparison of the two:
Similarities
High strength: 7050 aluminum bar and 7075 aluminum rod are both high-strength aluminum alloys with good mechanical properties and are suitable for manufacturing structural parts that bear high loads.
Heat-treatable: Both can be further strengthened through heat treatment, increasing the hardness and strength of the material.
Widely used: In aerospace, high-speed trains, ships and other fields, 7050 aluminum bars and 7075 aluminum rods are widely used to manufacture various high-strength, high-heat-resistant structural parts.
Differences
Chemical composition:
The main alloying element of 7050 aluminum alloy is zinc, and it also contains a certain amount of copper and other trace elements.
7075 aluminum alloy mainly contains zinc, magnesium, copper and other elements. The zinc content is between 5.1% and 6.1%, the magnesium content is between 2.1% and 2.9%, and the copper content is between 1.2% and 2.0%. .
Strength and heat resistance:
7050 aluminum rod has high strength and good heat resistance, but its strength is slightly lower than 7075 aluminum rod.
The strength of 7075 aluminum rod is very high, much better than mild steel. It is one of the strongest commercial alloys. It also has good heat resistance, but it may not perform as well in some high temperature environments as after special heat treatment. 7050 aluminum rod.
Tahan korosi:
7050 aluminum rod has good resistance to spalling corrosion and stress fracture corrosion, and long-term service evaluation shows that it maintains the same corrosion resistance.
7075 aluminum rod has ordinary corrosion resistance, but its corrosion resistance can be improved through appropriate surface treatment (such as aluminum cladding or other protective treatments).
Processing performance:
7050 aluminum rod shows good plasticity and toughness during processing, and can be used for various plastic processing such as stretching, bending, stamping, etc.
Although 7075 aluminum rods are easy to process, due to their higher strength, higher pressure and temperature conditions may be required during certain processing processes. At the same time, care must be taken to avoid problems such as stress corrosion cracking.
Application areas:
7050 aluminum bars are mainly used in the manufacturing of structural parts in aerospace, high-speed trains, ships and other fields, such as aircraft frames, bulkheads, beams, frames, etc.
7075 aluminum rod is widely used in aerospace, mold processing, mechanical equipment and other fields due to its high strength and good mechanical properties, such as aircraft structural parts, molds, fixtures, etc.
