7075 aluminum blocks are increasingly becoming a popular choice for industries that require durable, high-strength materials. Known for their exceptional mechanical properties, 7075 aluminum alloy blends lightweight characteristics with high load-bearing capabilities, making it ideal for various applications ranging from aerospace to sporting goods.
What is 7075 Aluminum?
7075 aluminum belongs to the 7000 series of aluminum alloys, which are primarily alloyed with zinc. It contains other elements like magnesium, copper, and chromium, contributing to its outstanding strength and resistance to corrosion. This alloy designation reflects the general inclusion of these alloying elements. The primary composition consists of:
- Zinc (5.1% - 6.1%)
- Magnesium (2.1% - 2.9%)
- Copper (1.2% - 2.0%)
- Chromium (not more than 0.28%)
Due to this unique makeup, 7075 aluminum blocks are especially favored in the production of components requiring medium to high strength.
