Engineered for weight-critical aerospace, defense, UAV, handheld electronics, and high-performance automotive platforms, this precision-milled enclosure cover is machined from high-performance wrought magnesium alloy (such as AZ31B or ZK60). Delivering up to a 33% reduction in mass compared to aluminum and 75% lighter than steel, magnesium combines an exceptional strength-to-weight ratio with superior electromagnetic shielding (EMI/RFI) and mechanical vibration damping
