FAQ

What specific advantages does the 3xxx series offer over the 1xxx series for deep drawing?

The 3xxx series, particularly alloys like 3003 and 3004, incorporates manganese, which increases the material's tensile strength by approximately 20% compared to the standard 1xxx series. This added strength, combined with excellent elongation, prevents tearing and wall thinning during aggressive deep drawing, making it vastly superior for manufacturing deep pots and pressure vessels.

Can you accommodate custom diameter requirements outside of standard tooling sizes?

Yes, our advanced CNC slitting and blanking equipment allows us to produce precise outer diameters ranging anywhere from 80mm to 1600mm. We can customize the exact diameter to match your specific mold requirements, which drastically reduces your edge scrap and improves your overall material utilization rate.

How do you ensure the aluminum circles remain completely flat and free of internal stress?

During the rolling and annealing processes, we utilize advanced tension leveling technology. Furthermore, precise temperature control during the tempering phase relieves internal metallurgical stresses. This guarantees that the discs remain perfectly flat and will not warp when subjected to secondary stamping or forming.

What measures are taken to guarantee the surface is ready for non-stick PTFE or PE coatings?

We employ a strict degreasing and surface washing protocol post-rolling to ensure zero residual rolling oils or carbon deposits remain on the metal. The resulting mill finish provides the optimal micro-roughness required for high-adhesion bonding with advanced chemical coatings like PTFE and PE, preventing peeling or blistering in the final product.

How flexible are your payment terms and minimum order quantities for new projects?

We understand the need for operational flexibility during the procurement phase. For standard stock items, we can accommodate orders as low as 300 KGS to support your prototyping and initial testing phases. For full customized production runs, our standard MOQ is 2500 KGS, though this is always open to negotiation based on project scope. We accept secure payment methods including Telegraphic Transfer (TT) and Letter of Credit (LC).
