Aluminum bar‌ is a solid, long-profile metal product made from extruded, rolled, or drawn aluminum alloys. Available in ‌round, square, rectangular, or hexagonal cross-sections‌, bars are valued for their ‌strength-to-weight ratio, and corrosion resistance‌.

As a professional steel supplier for export, JBHD have a full range of aluminum bar products, including the following series:

3-series Aluminum Bars:

Grade: 3003

Characteristics: It can be strengthened by heat treatment. It has medium plasticity in the annealed, freshly quenched, and hot states. It has good spot - welding weldability. There is a tendency to form intergranular cracks when gas welding and argon arc welding are used.

Application Scope: Aircraft structures (skins, frameworks, rib beams, bulkheads, etc.), aircraft, ships, transportation, rivets, missile components, truck wheel hubs, propeller elements, etc.

5-series Aluminum Bars:

Grades: 5052, 5754, 5083, 5056, etc.

Characteristics: It has good formability, corrosion resistance, weldability, and medium strength.

Application Scope: Used for manufacturing aircraft fuel tanks, oil pipes, as well as sheet - metal parts of transportation vehicles and ships, instruments, street - light brackets, rivets, hardware products, electrical appliance casings, etc. It is one of the most widely used anti - rust aluminum alloys.

6-series Aluminum Bars:

Grades: 6061, 6063, 6082, 6013, 6262, 6101

Characteristics: It can be strengthened by heat treatment. It has medium plasticity in the annealed, freshly quenched, and hot states. It has good spot - welding weldability. There is a tendency to form intergranular cracks when gas welding and argon arc welding are used.

Application Scope: Aircraft structures (skins, frameworks, rib beams, bulkheads, etc.), aircraft, ships, transportation, rivets, missile components, truck wheel hubs, propeller elements, etc.

7-series Aluminum Bars:

Grades: 7075, 7003, 7050, 7005, 7001, 7049

Characteristics: It has good plasticity after solution treatment. The heat - treatment strengthening effect is particularly good. It has high strength below 150°C and especially good low - temperature strength. Its welding performance is poor. There is a tendency to stress - corrosion cracking. It needs to be cladded with aluminum or other protective treatment before use.

Application Scope: Used for manufacturing aircraft structures and other high-stress structural
