M3 & M6 Aluminum Slugs: High-Precision Solutions for Small-Scale Applications

What Are M3 and M6 Aluminum Slugs?

M3 and M6 refer to industry-standard small-size aluminum slugs, commonly used in the production of:

• Lip balm tubes

• Mascara and eyeliner containers

• Single-dose pharmaceutical tubes

• Compact spray canisters or vials

• Small electronic housing parts

These slugs are typically produced in very small diameters, ranging from 10mm to 20mm, with thicknesses between 1mm and 4mm, depending on customer specifications.

Key Features of M3/M6 Slugs

🔩 Ultra-Small Size with High Consistency
Engineered for micron-level precision to ensure reliable performance in small-volume forming.

🌡 Excellent Annealing
Soft and clean surface, ideal for deep drawing and impact extrusion with minimal deformation.

🧪 Custom Alloy Options Available
Typically made from 1070, 1060, or 3003 aluminum, but alloy customization is possible depending on the final product.

💡 Optimized for Cosmetic and Pharma Use
Meets surface and hygiene standards for personal care and medical-grade packaging.

Application Scenarios

M3 and M6 aluminum slugs are widely adopted in:

• Premium cosmetic packaging

• Travel-size or sample tubes

• Electronic sensor shells

• High-precision fittings and mini-containers

Their small size allows for compact, lightweight final products without compromising material strength or appearance.
