Magnesium Alloy


Net shape, die cast magnesium reduces product costs – outperforms aluminum and plastic.

When you need strength, durability and light weight, magnesium die cast components deliver the perfect solution.

FisherCast is the leader in replacing aluminum parts with lower-cost net shape, flash-free small die cast magnesium components.  Where creep, strength and weight are concerned, magnesium is the clear choice.

Magnesium is the lightest of all structural metals, yet it has the highest strength-to-weight ratio.

  • Magnesium is 33% lighter than aluminum and 77% lighter than steel.
  • Excellent dimensional stability and consistent, predictable shrinkage rates ensure part-to-part consistency.
  • High fluidity allows for thin wall sections (a minimum 0.5 mm/.020") for reduced cost, increased production rates, complex, intricate detail and heat dissipation.
  • Magnesium has inherent EMI/RFI shielding properties, plus high dent and shock resistance.
  • Magnesium offers excellent vibration, noise dampening and creep resistant characteristics.


Tier I and Tier II suppliers and other OEM’s rely on FisherCast’s capabilities to add increased value to their magnesium die cast components:  Application Engineering, Finite Element Analysis (FEA), Prototyping and Modeling.

We use our design techniques and tooling capabilities to reduce non-value added material and consolidate multiple components to further reduce manufacturing costs, and improve component performance and quality.
