The 1050 Aluminum Sheet, available in both DC (Direct Chill) and CC (Continuous Cast) forms, is a highly versatile metal sheet known for excellent corrosion resistance, good conductivity, and superior workability. It is widely used in industries seeking lightweight yet durable materials for manufacturing, construction, and household applications.
What is 1050 DC or CC Aluminum Sheet?
The 1050 aluminum sheet typically refers to an aluminum alloy with a minimum 99.5% aluminum content, placing it in the 1xxx series, celebrated for exceptional corrosion resistance, excellent electrical and thermal conductivity, and high ductility.
- DC (Direct Chill) Casting: Features a casting process where molten metal solidifies via chilling water to form ingots with superior surface quality. DC sheets usually have better machinability and can be produced in thicker gauges.
- CC (Continuous Casting): Involves continuously casting while the molten metal solidifies during a downward passage through a mold producing thinner sheets with generally uniform thickness and high surface finish.
Functions & Features
- Outstanding Corrosion Resistance: Ideal for humid and corrosive environments.
- Excellent Workability and Formability: Easily fabricated, suited for bending, rolling, stamping, and welding.
- Superior Electrical and Thermal Conductivity: Common in electrical fittings and heat exchangers.
- Non-toxic & Recyclable: Safe for food and pharmaceutical containers and eco-friendly reuse.
