What are typical diameter ranges for aluminum round bars?
Standard diameters range from 3mm to 300mm. Common sizes include 6mm, 12mm, 25mm, and 50mm. Larger diameters (e.g., 150mm+) are used for heavy-duty applications. Tolerances follow ISO or ASTM standards. Custom diameters can be extruded for specialized needs.
How thick are standard aluminum flat bars?
Flat bars typically range from 1mm to 50mm in thickness. Widths vary from 10mm to 300mm. Popular sizes include 3mm×20mm and 6mm×50mm. Thinner bars are used for lightweight framing. Thicker bars suit structural supports.
What lengths are aluminum bars usually sold in?
Standard lengths are 1m, 3m, and 6m. Custom cuts are available for specific projects. Longer bars (up to 12m) exist for industrial use. Shipping constraints may limit maximum length. Precision-cut bars reduce material waste.
Do alloy types (e.g., 6061 vs. 7075) affect bar dimensions?
No-alloys share the same dimensional standards. 6061 bars are common for machining. 7075 bars prioritize strength over workability. Choice depends on mechanical needs, not size. Surface finishes may vary by alloy.
Are there international standards for aluminum bar dimensions?
Yes, ASTM (U.S.), DIN (EU), and GB/T (China) define standards. Metric and imperial units are both used. Tolerances differ slightly by region. Export-oriented mills often comply with multiple standards. Always verify specs with suppliers.
