6061 Aluminum Plate for Auto Bumpers (Anti-Collision Beams)

-
图片
  Auto bumpers (anti-collision beams) are critical safety components that absorb impact energy and protect vehicle bodies during collisions. They require materials that balance high strength, impact resistance, and lightweight— 6061 aluminum plate for auto bumpers   (a 6-series aluminum-magnesium-silicon alloy) meets these demands perfectly. Henan Mingtai Aluminum Co, Ltd. (stock code: 601677), a leading aluminum processor with over 20 years of experience, produces high-quality 6061 aluminum plates (primarily T6 temper) that comply with strict automotive safety standards. 1. Core Advantages of 6061 Aluminum Plate for Auto Bumpers 6061 aluminum plate (T6 temper) is engineered to address the key challenges of auto bumper design, offering three critical advantages: Exceptional Strength & Impact Absorption: Auto bumpers need to withstand low-to-medium speed collisions (15-40 km/h) without permanent deformation. 6061-T6 aluminum plate has a tensile strength of 276-310 MPa and y...
