Aluminum Turbo Charger Compressor Housing Premium Casting Services Product

In the high-performance automotive industry, aluminum turbocharger compressor housings represent a critical component where advanced metallurgy meets precision manufacturing. Our premium casting services specialize in producing housings that deliver exceptional performance, durability, and reliability under extreme operating conditions.

Advanced Aluminum Material Technology

Our compressor housings utilize high-strength aluminum-silicon alloys specifically engineered for turbocharger applications. These alloys, including A356-T6 and 354, offer an optimal balance of lightweight characteristics and mechanical strength. The material composition provides:

• Excellent thermal conductivity for efficient heat dissipation

• High specific strength maintaining structural integrity at elevated temperatures

• Superior corrosion resistance against automotive fluids and environmental exposure

• Outstanding fatigue resistance withstanding pressure cycling and vibrational stresses

The aluminum microstructure is carefully controlled through specialized heat treatment processes, achieving tensile strengths exceeding 45,000 psi and yield strengths above 35,000 psi while maintaining elongation properties of 3-5% for improved impact resistance.

Precision Manufacturing Processes

High-Pressure Die Casting

Our vacuum-assisted high-pressure die casting process ensures superior housing quality with:

• Reduced porosity levels below 1% through advanced vacuum systems

• Enhanced dimensional stability maintaining critical tolerances within ±0.002 inches

• Optimized wall thickness as thin as 2.5mm for weight reduction without compromising strength

• Superior surface finish typically achieving Ra 32-63 microinches in as-cast condition

Secondary Machining Operations

Precision CNC machining completes the manufacturing process:

• 5-axis simultaneous machining of complex volute geometries and mounting surfaces

• Precision boring of compressor wheel clearance maintaining concentricity within 0.001 inches

• Thread forming for sensor ports and mounting points ensuring leak-free connections

• Surface enhancement through shot peening for improved fatigue resistance

Enhanced Performance Characteristics

Our aluminum compressor housings deliver exceptional operational benefits:

• Maximum pressure capability exceeding 3.5 bar for high-boost applications

• Temperature resistance maintaining dimensional stability up to 250°C (482°F)

• Reduced weight approximately 35-40% lighter than equivalent cast iron components

• Improved aerodynamic efficiency through optimized volute design and surface finish

• Excellent heat dissipation preventing heat soak and maintaining charge air density
