Кіраўніцтва па таўшчыні алюмініевага ліста: Як указаць правільны калібр
Specifying aluminum sheet thickness sounds simple, but it is where many buyers get tripped up. Gauge numbers, millimeters, “ліст” versus “талерка” boundaries and the difference between nominal and actual thickness all matter. Get it wrong and the part either cannot be formed or costs more than it should.
Sheet vs Plate: Where Is the Line?
In most commercial practice, aluminum under 6.0 mm is called sheet and 6.0 mm and above is called plate. This is a practical convention, not a strict standard, but it matters when you ask a supplier for a quote because pricing, tooling and lead time differ. Our sheet range includes 1060 ліст, 3003 ліст і 5052 ліст; thicker structural and aerospace stock is listed under our 6061 Пласціна Т6 і 7075 Пласціна Т6.
Common Gauges and Their Typical Uses
| Таўшчыня | Звычайнае выкарыстанне |
|---|---|
| 0.3 – 0.8 мм | Foil, capacitor, ўпакоўка, глыбокая выцяжка |
| 1.0 – 2.0 мм | Посуд, прыкметы, жолаб, дэкаратыўныя панэлі |
| 2.0 – 4.0 мм | Tank skins, trailer panels, алмазны пратэктар |
| 4.0 – 6.0 мм | Marine plate, дарожныя знакі, structural skin |
| 6.0 – 50 мм | Machined plate, аснастка, свяцільні, аэракасмічны |
Nominal vs Actual Thickness
Aluminum sheet is sold by nominal thickness, but actual thickness varies by gauge tolerance. А “2.0 мм” sheet can be 1.88 – 2.04 mm in commercial quality. If your part is CNC-machined to a tight dimension, specify both nominal and allowed tolerance (for example, 3.0 ± 0.10 мм) and we will confirm the mill’s capability. For tread (дыямент) талерка, remember the listed thickness usually refers to the base thickness, not the peak of the pattern.
What Else to Specify
Beyond gauge, buyers should also specify: alloy and temper (1060 H14, 3003 H24, 5052 H32, 6061 Т6, г.д.), width and length (standard sheets are 1220 × 2440 мм або 1500 × 3000 мм), surface finish (аздабленне млына, шчоткай, анадаваны, PVC protected) and packaging (pallet, bundle, anti-corrosion paper). Sending a single number — “give me 2 mm aluminum” — leaves too much room for misinterpretation.
