We maintain a complete inventory of aerospace-grade and commercial-grade aluminum alloy materials to ensure the best performance and cost suitability:
6061-T6
Most Versatile
The most versatile structural alloy, offering excellent machinability, weldability, and corrosion resistance. Suitable for most mechanical components, tooling fixtures, and enclosures.
7075-T6
Ultra High Strength
An ultra-high-strength aluminum alloy with strength comparable to many steels. An ideal choice for aerospace, high-performance sporting goods, and critical load-bearing structures.
5052-H32
Marine Grade
Offers excellent corrosion resistance (especially in marine environments) and formability. Commonly used for ship and vehicle trim, and electronic enclosures.
2024-T3/T4
Aerospace
Provides good fatigue strength and strength-to-weight ratio. Widely used in aircraft structural components, truck wheels, and other high-strength applications.
MIC-6 / Cast Aluminum Tooling Plate
Precision
A precision-ground, pre-hardened plate with stress-free internal structure, ideal for precision substrates, fixtures, and molds.
Frequently Asked Questions
Q What is the difference between 6061-T6 and 7075-T6 aluminum alloys?
A 6061-T6 is the more versatile, cost-effective option with excellent machinability and weldability, suited for general structural use. 7075-T6 offers significantly higher strength — comparable to many steels — making it ideal for aerospace and high-performance applications where maximum strength-to-weight ratio is critical.
Q Which aluminum alloy is best suited for marine or outdoor environments?
A 5052-H32 is the top choice for marine and outdoor applications due to its outstanding corrosion resistance, particularly in saltwater environments. It is widely used for ship components, vehicle trim, and enclosures exposed to harsh conditions.
Q Is 2024-T3/T4 aluminum weldable?
A 2024-T3/T4 has limited weldability compared to alloys like 6061. It is primarily valued for its high fatigue strength and excellent strength-to-weight ratio, making it a preferred material for aircraft structural parts and high-stress applications rather than welded assemblies.
Q What makes MIC-6 Cast Aluminum Tooling Plate different from standard aluminum plate?
A MIC-6 is a precision-ground, pre-hardened cast aluminum plate with a stress-free internal structure. Unlike standard rolled aluminum plate, it offers superior dimensional stability and flatness, making it ideal for precision fixtures, substrates, and molds where tight tolerances are required.
Q Do you offer both aerospace-grade and commercial-grade aluminum materials?
A Yes. We maintain a complete inventory of both aerospace-grade alloys (such as 7075-T6 and 2024-T3/T4) and commercial-grade alloys (such as 6061-T6 and 5052-H32), allowing us to recommend the most suitable material based on your performance requirements and budget.
Q How do I choose the right aluminum alloy for my project?
A The best alloy depends on your specific requirements: for general machined parts, 6061-T6 is the most practical choice; for maximum strength in aerospace or sporting applications, consider 7075-T6; for corrosion-prone environments, 5052-H32 is recommended; for fatigue-critical structures, 2024-T3/T4 is preferred; and for precision tooling or fixtures, MIC-6 tooling plate is the optimal solution.
Finishes and Post-Processing Options
The zinc alloy substrate is highly suitable for various surface treatments to enhance decoration, protection, or functionality:
Electroplating: Such as chrome, nickel, gold, or silver plating, providing a highly decorative appearance, excellent wear and corrosion resistance. This is the most common choice.
