Equipment case material selection—aluminum versus steel—involves tradeoffs across weight, strength, corrosion resistance, and cost. Aluminum cases weigh 50-60% less than equivalent steel cases while steel provides superior impact resistance and security.
Aluminum Cases
Aluminum 5052-H32 offers excellent corrosion resistance, formability, and weldability. With density of 2.68 g/cm³ versus steel’s 7.85 g/cm³, aluminum cases reduce shipping costs and field handling fatigue. Anodized finishes provide additional surface hardness and wear resistance.
Steel Cases
Steel cases using cold-rolled or galvanized steel provide maximum physical security. Steel’s 200 GPa elastic modulus versus aluminum’s 69 GPa provides 3x stiffness for equivalent section. Powder coating provides corrosion protection for steel cases in harsh environments.
Industrial Applications
Equipment cases for the CBK Crimper and Hydraulic Oil Filter Press protect precision equipment during field deployment. The Double Stage Oil Purifier requires protective transport cases. Oil Testing equipment includes portable cases. The Oil Regeneration System uses rugged cases for field service.
