1050 Aluminium-Legierung

What Is 1050 Aluminum Alloy?

1050 aluminum alloy (UNS A91050) is a commercially pure aluminum grade in the 1000 series, with a minimum aluminum content of 99.5%. It is a non-heat-treatable alloy — its strength is developed through strain hardening (H-tempers) rather than heat treatment. The high purity gives 1050 its defining characteristics: excellent corrosion resistance, very high electrical and thermal conductivity, outstanding formability in the annealed (O) temper, and a clean, bright surface finish that takes well to anodizing.

1050 is often specified where electrical conductivity, thermal transfer, formability, or corrosion resistance matter more than tensile strength. Typical applications include electrical busbars and conductors, heat exchangers, lighting reflectors, chemical storage tanks, roofing and cladding, and a wide range of deep-drawn or spun components. Linsy supplies 1050 aluminum in sheet, coil, plate, bar, tube, wire, and custom profiles, with MTC reports provided for every order and SGS test reports available on request.

Mechanische Eigenschaften je nach Temperierung

1050 is a strain-hardenable alloy. Strength increases as the material is cold-worked through the H-temper series. The following values are typical for 1050 aluminum and are intended for material comparison and preliminary selection. Final design values should be verified against the applicable standard and the MTC for the specific lot.

Temperament	Zugfestigkeit (MPa)	Streckgrenze (MPa)	Dehnung (%)	Typische Verwendung
1050-O (Annealed)	75 – 95	≤ 35	≥ 35	Deep drawing, spinning, severe forming
1050-H111 / H112	80 – 100	≥ 40	≥ 25	General fabrication, lightly worked parts
1050-H14 (Half Hard)	100 – 120	≥ 80	≥ 6	General structural and formed parts
1050-H18 (Full Hard)	120 – 150	≥ 110	≥ 3	Parts requiring highest strength from cold work

Leitfaden zur Auswahl der Härtung

Because 1050 is non-heat-treatable, temper selection is based on the amount of strain hardening needed for your application. The following guide helps you choose the right temper for common use cases.

Temperament	Zustand	Wesentliche Merkmale	Am besten für
O	Fully annealed	Softest, maximum formability, lowest strength	Deep drawing, spinning, reflective parts, cookware
H111 / H112	Slightly strain hardened	Moderate strength, good formability	General sheet metal work, piping, lightly formed parts
H14	Half hard	Good balance of strength and formability	General fabrication, cladding, roofing, structural panels
H18	Full hard	Highest strength from cold work, low ductility	Rigid parts, stiffeners, non-formed components

Key Characteristics of 1050 Aluminum

Excellent Electrical & Thermal Conductivity

With approximately 61% IACS (International Annealed Copper Standard) electrical conductivity and around 222 W/m·K thermal conductivity, 1050 is widely used in electrical and thermal management applications. It is a cost-effective alternative to copper for busbars, cable sheathing, transformer windings, heat exchanger fins, and heat sinks.

Hervorragende Korrosionsbeständigkeit

Like all high-purity aluminum grades, 1050 forms a strong, self-healing oxide layer that provides excellent resistance to atmospheric, industrial, and marine corrosion. It also resists many chemicals, including nitric acid and hydrogen peroxide, making it suitable for chemical storage and processing equipment.

Superior Formability & Workability

In the O temper, 1050 is exceptionally soft and ductile, excelling in deep drawing, spinning, stamping, and bending operations. This makes it a preferred material for lighting reflectors, cookware, decorative trim, and complex shaped components that require severe forming without cracking.

Weldability & Machinability

1050 is readily weldable using TIG, MIG, and resistance welding processes. The O temper is preferred for welded assemblies to avoid strength loss in the heat-affected zone. Machining 1050 requires sharp tools and proper clearance; it is gummy compared to alloyed grades but produces good surface finish when properly cut. Anodizing produces a bright, decorative finish on 1050 due to its high surface purity.

Gemeinsame Anwendungen

1050 aluminum is a versatile, cost-effective material used across a wide range of industries where high conductivity, corrosion resistance, and formability are more important than high strength.

Chemische Verarbeitung	Storage tanks, piping, vessels for nitric acid handling	Chemical resistance, weldability, purity
Lighting	Reflectors, lamp housings, LED heat sinks	High reflectivity, formability, thermal conductivity
Automotive & General Engineering	Non-structural body panels, heat shields, gaskets, spacers	Formability, corrosion resistance, light weight
Food & Pharmaceutical	Brewing equipment, food contact tanks, packaging	Non-toxic, hygienic, corrosion resistant

Hinweise zur Bearbeitung und Oberflächenveredelung

Linsy’s Shenzhen factory supports a range of processing and value-added services for 1050 aluminum. Because 1050 is soft and gummy, proper tooling and feed rates are important for achieving clean results.

• CNC Machining: 1050 machines well with sharp carbide tooling and appropriate cutting speeds. It produces a fine surface finish but can be gummy at lower cutting speeds.
• Laser Cutting: 1050 cuts cleanly with fiber laser. Edge quality is excellent for a pure aluminum grade. Minimum recommended thickness depends on laser power; consult Linsy for specific limits.
• Welding: 1050 is readily weldable with TIG or MIG. O-temper material is preferred for welded assemblies. Post-weld annealing may be considered if maximum formability is needed after welding.
• Eloxieren: 1050 produces a bright, clear anodized finish due to its high surface purity. It is commonly specified for decorative trim and reflective surfaces.
• Polieren: The pure, silvery surface takes an excellent polish and is often used for decorative applications and lighting components.

1050 Aluminum FAQ

What is 1050 aluminum alloy used for?

1050 aluminum is commonly used in electrical busbars and conductors, heat exchanger fins, roofing and cladding, chemical storage tanks, lighting reflectors, cookware, and a wide range of deep-drawn or spun components where formability and corrosion resistance matter more than high strength.

Is 1050 aluminum heat-treatable?

No. 1050 is a non-heat-treatable aluminum alloy. Its strength is developed through strain hardening (H-tempers) rather than heat treatment. The common tempers are O (annealed), H111, H112, H14, and H18.

What is the difference between 1050 and 1060 aluminum?

Both are 1000 series pure aluminum alloys. 1050 has a minimum aluminum content of 99.5%, while 1060 has a minimum of 99.6%. The slightly higher purity of 1060 gives it marginally better electrical and thermal conductivity, but the differences are small for most commercial applications.

Can 1050 aluminum be welded?

Yes. 1050 is readily weldable using TIG, MIG, and resistance welding. The O temper is preferred for welded assemblies to preserve maximum ductility in the heat-affected zone. Post-weld stress relief annealing may be considered for severely formed parts.

Can 1050 aluminum be anodized?

Yes. 1050 produces a bright, clear anodized finish due to its high surface purity. It is commonly specified for decorative trim, lighting reflectors, and architectural applications where appearance matters.

What is the electrical conductivity of 1050 aluminum?

1050 aluminum has approximately 61% IACS (International Annealed Copper Standard) electrical conductivity and around 222 W/m·K thermal conductivity, making it suitable for electrical busbars, transformer windings, and thermal management components.
