Quick selection guide for 1070 aluminum sheet plate
GNEE is China's top manufacturer and supplier of 1070 aluminum plate and sheet, offering large-scale bespoke manufacturing as well as ready-to-ship stock quantities to fulfill both bulk and small-batch requirements.
For electrical conductivity and heat transfer, select 1070-O or 1070-H14; for improved contact and cooling, utilize a mill finish or anodized natural surface.
For a high reflectivity appearance, use mirror-finish 1070 (or 1085) for lighting fixtures, reflectors, and ornamental panels.
For deep drawing and bending, use soft temper O or low temper H12/H14 with a bend radius of at least 1-2 times the sheet thickness.
For outdoor corrosion resistance, 1070 has natural corrosion resistance; anodizing or clear coating enhances endurance.

F a q about 1070 aluminum sheet plate
1.What is the 1070 aluminium grade?
1070 is a high-purity aluminum alloy with at least 99.7% Al concentration. It has excellent electrical and thermal conductivity, corrosion resistance, and is commonly used in busbars, capacitors, and heat dissipation components.
2.How do I tell whether my aluminum is 5052 or 6061?
5052 is part of the 5xxx series (Al-Mg), which is noted for its high corrosion resistance and weldability and is commonly used in marine and chemical equipment. 6061 is a 6xxx series (Al-Mg-Si) alloy with excellent strength and machinability, commonly used in aerospace and structural parts. A material test certificate (EN 10204 3.1) will establish the grade.
3.What is the yield strength of 1070 aluminum?
The normal yield strength of 1070 aluminum is around 40 MPa (EN 485-2), depending on temper state. It is less expensive than the 5xxx and 6xxx series alloys, but still adequate for electrical and ductile applications.
4.What's the difference between 1100 and 6061 aluminium?
1100 is a commercially pure aluminum (99% minimum), with good corrosion resistance and formability. It is mostly utilized in chemical equipment and the food sector. 6061 is a heat-treatable alloy with excellent strength and hardness, making it ideal for aerospace, automotive, and structural applications.
