Common Sourcing Challenges & How We Solve Them
| Pain Point | Our Solution |
|---|---|
| Inconsistent alloy composition & tolerances | Every aluminium block batch tested with spectrometer; dimensional inspection report provided. |
| Long lead times (8–12 weeks from many suppliers) | Standard sizes ready in 7–15 days; OEM orders 20–30 days. Express shipping available. |
| High MOQ forcing large upfront inventory | MOQ as low as 200 kg for trial orders; flexible ramp-up to full container loads. |
| Lack of after-sales support & technical documentation | Dedicated account manager, mill certificates, and 24/7 online support. |
Aluminium Block Specifications & Common Applications
Our aluminium block range covers the most widely used wrought alloys for CNC machining, welding, and finishing. Below is a quick reference table:
| Alloy | Temper | Key Properties | Typical Applications |
|---|---|---|---|
| 6061-T6 | T6 / T651 | Good machinability, weldable, corrosion resistant | Automotive brackets, structural frames, marine components |
| 6063-T5 | T5 / T6 | Excellent extrudability, smooth surface finish | Architectural profiles, window frames, heat sinks |
| 7075-T6 | T6 / T7351 | High strength-to-weight ratio, stress corrosion resistant (T73) | Aerospace fittings, gear parts, mold bases |
| 2024-T3 | T3 / T351 | High fatigue strength, good machinability | Aircraft structures, military equipment, racing parts |
| 5083-H116 | H116 / H321 | Exceptional marine corrosion resistance, high weldability | Shipbuilding, pressure vessels, offshore platforms |
* All mechanical properties are based on standard mill data. Actual values may vary slightly per batch – refer to the material test certificate (MTC) supplied with each order.

What Our Buyers Say
James Miller
Procurement Manager, Midwest Machining Inc. (USA)
“We were skeptical about sourcing aluminium block from China due to past quality issues. TJJ provided test samples that matched our specs perfectly. Their QC reports are thorough, and delivery for 2 tons of 6061 arrived in 12 days. Now a regular partner.”
Sofia Reyes
Brand Owner, Aerokit Components LLC (Florida)
“Needed 7075 blocks for aerospace prototypes with tight tolerances. TJJ’s engineering team helped me choose the right temper and even expedited the first order. The MTC and third-party test results gave me confidence. Highly recommend for technical buyers.”
David Kim
Sourcing Agent, Kim Industrial Supply (California)
“I handle multiple clients with different alloy needs. TJJ’s inventory of 6061, 6063, and 7075 means I can consolidate orders. Their MOQ flexibility allowed me to start small and then scale. Responsive communication, good prices, and the blocks are always clean and well-packed.”
Linda Zhao
Operations Director, GreenMart Furniture (Canada)
“We use extruded 6063 aluminium block for modern furniture frames. TJJ provided custom anodized finishes (clear, bronze, black) with consistent color. Lead time was 18 days, exactly as promised. Excellent after-sales support when we needed a replacement for a damaged piece.”
Andrew Sullivan
Owner, Sullivan Custom Works (Texas)
“I run a small CNC job shop and need short-run aluminium block quantities. TJJ’s low MOQ of 200 kg let me secure 6061-T6 without overstocking. Their cuts are accurate to ±0.05 mm on key dimensions, saving me machining time. Will definitely reorder.”
