Alloy mast spars - All aluminium alloys have the same stiffness. The only way to get a stiffer alloy mast is to increase the diameter and/or wall thickness. The GROOVY mast tubes we stock have a medium temper that enables them to be pre-bent easily to the shape required without great danger of breakage. The 11 mm diameter round mast tube we stock is a very hard alloy (7075 grade T6 temper) and is difficult to add pre-bend to. To ease this process we have a mast bending tool. There is a thorough explanation of this subject in the FAQs section.
