Is J-B Weld a good choice to repair aluminium?

J-B Weld is a highly reputable company that specializes in ultra-strong glues that can be used on metals such as aluminum in place of welding. While it works well for small-scale repairs, it is not recommended for large-scale repairs, where true welding is necessary.

J-B Weld uses epoxy adhesives to manufacture glue that can be used to bond broken metals, including aluminum. Because welding is a complex process that requires the work of a professional, J-B Weld is a popular choice for do-it-yourself solutions. It is intended for small-scale repairs of non-moving metal parts, such as a cracked automobile tailpipe. It is not intended for large-scale repairs, such as a broken bicycle frame.
