Products Description
This Aluminium Alloy Latch Ring is engineered for demanding assemblies where strength, stability, and consistent mechanical performance are essential. Manufactured from aerospace-grade 7075 aluminum and finished with a MIL-C-5541 Type II Class 1A chem film coating, the part delivers long-term durability while maintaining precise dimensional accuracy. Its lightweight design and reliable strength make it a preferred choice for high-performance CNC aluminum components.
Precision Dimensions & Machining Details
The ring is produced using multi-axis CNC machining to ensure stable geometry and a dependable fit with mating parts:
Thickness: 1.280 in
Outer Diameter: Ø4.830 in
Threaded Holes: Six holes tapped 0.190-24 UNC-2B
Radial Runout: Three key diameters on the same axis hold runout within 0.010 in
These tolerances support smooth operation, proper alignment, and repeatable assembly quality.
Material Specifications
The Aluminium Alloy Latch Ring can be supplied in various 7075 tempers, depending on structural requirements:
7075-T6, T651, T7351, T6511, T73511, T6510
All materials comply with:
AMS 4045, 4078, 4122, 4123, 4124, 4168, 4169
ASTM B211 / ASTM B221
These specifications ensure excellent strength-to-weight performance, making the latch ring suitable for aerospace machined parts, advanced equipment, and high-load rotating mechanisms.

FAQ
Q: What applications is the Aluminium Alloy Latch Ring suitable for?
A: The latch ring is commonly used in aerospace equipment, precision instruments, and mechanical locking systems. Its 7075 material strength and chem film coating make it ideal for assemblies that require both lightweight construction and high durability.
Q: Do you support custom dimensions or thread types?
A: Yes. Since the part is produced through CNC machining, dimensions, thread sizes, and mounting features can be customized according to your drawings. We regularly provide custom variations for OEM projects and specialized CNC aluminum components.
Q: Can this latch ring be anodized instead of chem film?
A: If your project requires a specific surface finish, anodizing, hard anodizing, or clear coating can be applied. However, the standard version uses MIL-C-5541 Type II Class 1A chem film for its corrosion resistance and conductivity.
Q: What inspection methods are used to ensure accuracy?
A: Critical dimensions-such as outer diameter, thickness, thread quality, and the 0.010 in radial runout-are checked using CMM measurement, thread gauges, and calibrated metrology tools. This ensures consistency for high-precision or aerospace-grade assemblies.
Q: What information do I need to provide for a quotation?
A: To prepare an accurate quote, please include your technical drawing, material requirements, quantity, surface finish needs, and any special tolerances. Our engineering team will review the details and respond quickly with a competitive offer tailored to your application.
