Surface Protection Prep<\/strong><\/td>\n2024 has poor corrosion resistance. We machine parts to be immediately ready for Alodine (Chem Film) or Cladding.<\/td>\nWe coordinate post-processing to ensure parts are coated before oxidation begins, meeting Mil-Spec standards.<\/td>\n<\/tr>\n
Complex Pocketing<\/strong><\/td>\nDeep pocket milling to reduce weight while maintaining structural integrity.<\/td>\nOur high-speed spindles remove material efficiently while maintaining thin wall stability (down to 1mm).<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Fabrication Guidelines for 2024 Aluminum<\/h3>\n

Corrosion Sensitivity:<\/strong>
\n2024 contains high Copper (4.4%), making it susceptible to corrosion. Tip:<\/strong> It is almost always anodized or chemically conversion coated (Alodine). “Alclad” sheets (pure aluminum coated) are often used for skins.<\/p>\n

Machinability:<\/strong>
\n2024 machines very well (better finish than 6061) producing small chips. However, the copper content can be abrasive to tools. Tip:<\/strong> Use sharp carbide tools and flood coolant.<\/p>\n

Weldability:<\/strong>
\nNot recommended for welding.<\/strong> Welding causes hot cracking and significantly reduces corrosion resistance. Tip:<\/strong> Use fasteners (rivets\/bolts) for assembly instead.<\/p>\n<\/div>\n

Primary Applications<\/h3>\n

Aircraft Structures<\/strong>
\nFuselage skins, wing tension members, and bulkheads where high tensile strength and fatigue resistance are paramount.<\/p>\n

Precision Fittings<\/strong>
\nHydraulic manifolds and valve bodies within the aviation sector.<\/p>\n

High-Stress Parts<\/strong>
\nGears and shafts in machinery where weight savings over steel are required but 6061 is not strong enough.<\/p>\n

Scientific Instruments<\/strong>
\nOrthopedic braces and veterinary equipment requiring stiff, lightweight frames.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
