What Is 1050A H14 Aluminium Plate
1050A H14 aluminium plate belongs to the 1000 series of commercially pure aluminium, containing approximately 99.5% aluminium. The H14 designation indicates a strain-hardened temper produced by cold working to a moderate level, without subsequent annealing. Because the alloy is non-heat-treatable, its strength comes entirely from cold working, which also gives the material consistent behavior and long-term dimensional stability. The result is a bright, corrosion-resistant plate with high ductility, widely recognized as EN AW-1050A and equivalent to AA1050 or Al99.5 grades.
Key Characteristics and Performance
1050A H14 offers excellent corrosion resistance in humid and mildly chemical environments, high ductility that allows complex forming without cracking, and good weldability with standard TIG and MIG processes. Its density is about 2.71 g/cm3, and it delivers high thermal and electrical conductivity, making it useful for heat and electrical applications. The strain-hardened temper raises tensile strength into the range of about 105-145 MPa while keeping the surface bright and reflective, which suits both functional and decorative uses.
Chemical Composition
The composition of 1050A is tightly controlled: aluminium balance of about 99.5%, silicon up to 0.25%, iron up to 0.40%, copper up to 0.05%, manganese up to 0.05%, magnesium up to 0.05%, zinc up to 0.07%, and titanium up to 0.05%. These tight impurity limits preserve the alloy's corrosion resistance, conductivity, and formability. Because the material is nearly pure aluminium, it anodizes cleanly and accepts surface coating processes well.
Common Applications
Typical applications include chemical processing tanks and equipment, food and beverage containers and utensils, architectural cladding, trims and decorative panels, lamp reflectors and lighting components, heat exchangers, and electrical components. The alloy is especially suitable for environments that require high corrosion resistance and easy forming, where high mechanical strength is not the primary requirement. Its recyclability and non-magnetic properties add value in sustainable and specialized projects.
Specifications and Customization
1050A plate is commonly supplied in tempers such as O, H12, H14, H16, H18, H22, H24, and H26, in thicknesses from 0.2 mm to 500 mm, widths from 1000 mm to 2650 mm, and lengths up to about 2500 mm. Production follows standards such as ASTM B209, EN 485, and GB/T 3880. Customization includes precise cutting to required dimensions, a wide thickness range for both lightweight and structural uses, and surface finishes such as mill finish, polished, anodized, and coated, with protective packaging for transport.
FAQ
What does H14 mean in 1050A H14 plate?
H14 means the plate is strain-hardened by cold working to a moderate level, giving a balance of strength and ductility. The alloy cannot be hardened by heat treatment, only by cold work.
Is 1050A the same as 1050?
They are very similar. 1050A is the European designation EN AW-1050A, while 1050 is the general designation for the same 99.5% aluminium grade. Equivalent names include AA1050 and Al99.5.
Can 1050A H14 be welded?
Yes. The alloy welds well with TIG and MIG using appropriate filler such as 1100 or 4043, and it also supports brazing and soldering.
Is 1050A suitable for food contact?
Yes, in appropriate applications. The high-purity alloy is non-toxic and is commonly used for food and beverage containers and utensils, subject to applicable food-contact regulations.
Why choose 1050A instead of a stronger alloy?
Choose 1050A when corrosion resistance, conductivity, reflectivity, and formability matter more than strength. It is also one of the most economical aluminium grades, which suits large-volume fabrication.
