When producing collapsible tubes, every small variation in raw material can lead to problems—wrinkling, cracking, or unplanned downtime. That’s why our 24.6×3.3 mm aluminum slugs are designed with consistency at their core.
Each slug is made from 99.7% pure 1070 aluminum and undergoes a carefully controlled annealing process. By holding temperature and cooling rates within narrow ranges, we ensure a uniform grain structure and ductility that supports deep drawing without tearing. The result: smoother forming, lower scrap rates, and a flawless surface ready for decoration.
Product Specifications

| Processing | Deep drawing, cold extrusion, surface oxidation | Compatible with high-speed lines and advanced surface finishes |
| Applications | Cosmetic tubes, pharma packaging, spray cans, capacitor shells, beverage bottles, auto parts | Proven versatility across industries |
| Storage | Store sealed and moisture-proof | Prevents oxidation or discoloration before use |
What Makes Ours Different
-
Dimensional Accuracy
Each batch is inspected with laser measurement systems to keep tolerances within ±0.05 mm. This precision ensures trouble-free feeding in high-speed transfer presses. -
Surface Quality
Slugs are polished and tested to meet Ra ≤ 0.5 µm surface roughness standards, giving you a clean base for anodizing, lacquering, or offset printing. -
Annealing Control
Our annealing furnaces use continuous temperature monitoring (±5 °C variation), creating uniform softness across every slug for predictable forming results. -
Proven Results
In a recent customer trial, scrap rates during extrusion dropped from 4.7% to below 1% after switching to our material.
Storage & Handling
For best performance, keep slugs in a dry, sealed environment. For long-term storage, we recommend vacuum-sealed packaging with optional anti-oxidation oil coating. A FIFO (First-In, First-Out) system is advised to maintain consistent quality.
