Buying advice

When selecting aluminum bars, consider the alloy (e.g., 6061 for general use, 6063 for decorative), temper (T6 for strength), dimensions, and surface finish. Check customer reviews for consistency and accuracy of dimensions. For structural applications, choose thicker bars from reputable brands. If you need to cut or weld, ensure the alloy is suitable.
