FAQ

Q1: What temper aluminum strip is best for transformer winding?

A: O soft temper 1060 aluminum strip is standard choice for transformer winding, good ductility and conductivity, easy for automatic winding machine.

Q2: Can you slit ultra narrow aluminum strip below 20mm?

A: Yes, minimum slitting width 15mm with burr-free smooth edge, precision tolerance ±0.05mm, suitable for small electronic accessories.

Q3: Is 3003 aluminum strip better for outdoor pipe wrapping?

A: Yes, 3003 alloy contains manganese element, has stronger anti-corrosion ability than 1060 pure aluminum, more suitable for outdoor humid and coastal environment.

Q4: What's your MOQ for aluminum strip coil?

A: Stock standard size MOQ 1 ton; customized alloy/size MOQ 3 tons. Small trial order acceptable for stock products.

Q5: Can aluminum strip be stamped into small hardware parts?

A: Yes, O/H14 temper aluminum strip supports deep stamping, bending and punching processing, no cracking after forming.
