Advantages of Thixomolded magnesium

Thixomolded magnesium is an enabling technology providing designers and engineers with a powerful material and process combination:

Thin Wall

Thixomolded magnesium parts are routinely molded with nominal wall thickness down to 0.020" (0.5 mm) providing high-strength precise moldings. Combining the process versatility and tooling capabilities of injection molding with outstanding material flow (L/D 600:1 in Spiral Flow tests), Thixomolded magnesium opens new intricate, space-efficient design possibilities in many markets.

Lightweight

With a material density of 0.065 lb/in^3 (1.81 g/cc), magnesium alloy AZ91D compares favorably with most injection molded thermoplastics and offers a significant increase in mechanical properties. Moreover, Thixomolded magnesium components are 34% lighter than aluminum and 76% lighter than steel.

High Strength

Stiffness, strength and durability are maximized as Thixomolded magnesium AZ91D components are 20-times stiffer than typical engineering thermoplastics (E=6.5 MSI / 45 GPa), have high strength-to-weight ratio (UTS=36 KSI / 243 MPa) and display superior impact response.

EMI Sheilding

Thixomolded magnesium housings and enclosures are electrically conductive (12%IACS) and provide effective EMI shielding without the use of fillers, plating or conductive paints. Greater than 85 dB of shielding is achieved at 0.039" (1.0 mm) wall thickness.

Thermal Management

Thin wall Thixomolded magnesium components optimize heat transfer with the excellent thermal conductivity of magnesium (k=42 Btu/ft-hr-F / 72 W/m-K)
supporting the needs of miniaturization and efficient thermal management.

Environmentally Friendly

All Magnesium TXM components–painted or unpainted–are fully recyclable. Magnesium is one of the earth’s most abundant elements—1 cubic mile of sea water contains approx. 12 Billion lbs. of magnesium.
