HSTF 3003 Aluminum Bar Temper
3003 O/F Aluminum Rod Bar
3003-O aluminum bars are in their softest state and have the highest ductility compared to other 3003 aluminum variants. They are particularly suitable for applications requiring high-volume forming and bending without cracking. H111 aluminum bars, after cold working, have slightly higher strength than O-tempered bars while maintaining good formability.
3003 F/H112 Aluminum Rod Bar
The 3003 H112 aluminum rod is similar to the F temper but allows for limited strain hardening or heat treatment under specific conditions. It maintains good workability with moderate strength, making it suitable for applications requiring good formability and corrosion resistance, such as construction, pipelines, and storage tanks.
3003 H12 Aluminum Rod Bar
3003 H12 aluminum rod undergoes moderate strain hardening, with its strength falling between the O temper (annealed) and fully hard (H18) states. It provides moderate strength and good formability, ideal for applications that require moderate strength and further processing, such as pipelines, chemical equipment, and storage tanks.
3003 H14/H16 Aluminum Rod Bar
3003 H14/H16 aluminum rods undergo more significant strain hardening, with strength between the annealed (O temper) and fully hard (H18) states. They offer good corrosion resistance and higher strength while maintaining good formability, making them suitable for medium-strength applications like metal products, chemical equipment, and tank containers.
3003 H18 Aluminum Rod Bar
The H18 temper represents the fully hardened state of 3003 aluminum bars, achieving maximum strength through complete strain hardening. Due to its high strength and low ductility, H18 aluminum bars are ideal for applications requiring no further processing, such as building materials and environments with high corrosion resistance requirements.
3003 H14 Aluminum Rod Bar
3003 H14 aluminum wire undergoes strain hardening treatment, resulting in medium strength, good formability, and corrosion resistance. It is widely used in the automotive industry, fastener manufacturing, and electronic equipment fields, and is especially suitable for manufacturing automotive brake rivets.
HSTF 3003 Aluminum Bar Shape
3003 Aluminum Round Bar
Diameter: 5-420mm
The round-section aluminum rod is the most commonly used shape. It can be extruded into microchannel aluminum tubes and custom decorative parts. It is typically used in heat exchangers, chemical equipment, and tank fittings.
3003 Aluminum Square Bar
Size: 10x10mm to 200x200mm
The square-section aluminum bar offers good machinability and weldability. It is suitable for a wide range of industrial fields such as construction, chemical processing, food processing, and machinery manufacturing.
3003 Aluminum Flat Bar
Size: 10x12mm to 100x250mm
The rectangular-section aluminum bar provides moderate strength, good corrosion resistance, and easy workability. It is commonly used in industrial applications that require corrosion resistance, formability, and adequate strength, such as construction, food processing, chemical equipment, and storage systems.
Application
Aerospace
Due to its good formability, excellent corrosion resistance, and high thermal conductivity, it is suitable for aircraft and spacecraft heat exchange systems, cooling pipes, liquid storage tanks, fuel pipes, gas processing equipment, and other non-load-bearing components.
Heat Exchangers
With a thermal conductivity of 180 W/m-K, it quickly transfers heat, improving heat transfer efficiency, and making it ideal for heat exchanger applications such as automotive radiators, air conditioning systems, air conditioner heat exchangers, and industrial heat exchangers.
Chemical Equipment
Storage Tanks
Widely used in applications requiring safe storage and high-strength sealing, such as food processing tanks, chemical tanks, and liquid storage tanks. The addition of manganese helps maintain stability and resist corrosion when in contact with liquid chemicals.
