Quick selection guide for 1070 aluminum sheet plate
Chalco is the leading manufacturer and supplier of 1070 aluminum plate and sheet in China, providing large-scale customized production as well as ready-to-ship stock sizes to meet both bulk and small-batch demands.
- For electrical conductivity & heat transfer – choose 1070-O or 1070-H14; use mill finish or anodized natural surface for better contact and cooling.
- For high reflectivity appearance – choose mirror-finish 1070 (or 1085) for lighting fixtures, reflectors and decorative panels.
- For deep drawing & bending – choose soft temper O or low temper H12/H14; recommended bend radius ≥ 1–2 × sheet thickness.
- For outdoor corrosion resistance – 1070 has natural corrosion resistance; anodizing or clear coating further improves durability.

Frequently asked questions about 1070 aluminum sheet plate
What is a 1070 aluminium grade?
1070 is a high-purity aluminum alloy with ≥99.7% Al content. It offers excellent electrical and thermal conductivity, good corrosion resistance, and is widely used for busbars, capacitors, and heat dissipation components.
How do I know if my aluminum is 5052 or 6061?
5052 belongs to the 5xxx series (Al-Mg), known for excellent corrosion resistance and weldability, often used in marine and chemical equipment. 6061 is a 6xxx series (Al-Mg-Si) alloy with higher strength and machinability, widely used in aerospace and structural parts. A material test certificate (EN 10204 3.1) can confirm the grade.
What is the yield strength of 1070 aluminum?
The typical yield strength of 1070 aluminum is about 40 MPa (EN 485-2), depending on temper condition. It is lower than 5xxx and 6xxx series alloys, but sufficient for electrical and ductile applications.
What is the difference between 1100 and 6061 aluminum?
1100 is a commercially pure aluminum (99% min), excellent in corrosion resistance and formability, mainly used for chemical equipment and food industry. 6061 is a heat-treatable alloy with higher strength and hardness, preferred for aerospace, automotive and structural parts.
What is the price of 1070 aluminum sheet?
The price depends on thickness, width, length, surface finish, temper and order quantity. For the latest factory-direct price, please contact Chalco with your specifications.
How much does 1070 aluminum sheet cost?
1070 aluminum sheet cost is usually quoted per kg or per ton, and varies with alloy temper, processing, and delivery terms. Chalco offers competitive pricing with both stock sizes and custom production.
