7075-T6 Machining Capabilities<\/h3>\n\n\n\n\n\n\n\n\n
Capability<\/th>\nTechnical Description<\/th>\nJucheng Advantage<\/th>\n<\/tr>\n<\/thead>\n
High-Precision Milling<\/strong><\/td>\n7075 is harder than 6061, resulting in better chip breaking and superior surface finishes directly off the machine.<\/td>\nWe achieve mirror-like finishes (Ra 0.4) on 7075 parts without manual polishing, ideal for cosmetic aerospace components.<\/td>\n<\/tr>\n
Thin-Wall Structural Parts<\/strong><\/td>\nDue to its high strength, 7075 can be machined into very thin walls (0.5mm) without collapsing or bending.<\/td>\nOur 5-axis machines utilize adaptive tool paths to maintain rigidity while removing up to 90% of the material for lightweighting.<\/td>\n<\/tr>\n
Complex Gear Machining<\/strong><\/td>\nMachining intricate gears and splines that require high fatigue strength and wear resistance.<\/td>\nWe use specialized gear hobbing and 4-axis milling strategies to produce 7075 gears that rival steel in strength-to-weight ratio.<\/td>\n<\/tr>\n
Stress-Relieved Milling<\/strong><\/td>\nUsing 7075-T651 plate to minimize movement during heavy hogging operations.<\/td>\nGuarantees flatness on large aircraft bulkheads and mold bases.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Fabrication Guidelines for 7075 Aluminum<\/h3>\n

Weldability Warning:<\/strong>
\nUnlike 6061, 7075 is generally considered non-weldable<\/strong> (prone to micro-cracking). Tip:<\/strong> Parts should be designed as single-piece machined components or fastened\/bonded rather than welded.<\/p>\n

Anodizing Considerations:<\/strong>
\n7075 contains high amounts of Zinc. While it can be anodized, Clear Anodizing may result in a slightly yellowish tint compared to the silver of 6061. Hard Anodizing (Type III) works excellent for wear resistance.<\/p>\n

Corrosion Resistance:<\/strong>
\n7075 has lower corrosion resistance than 6061. Tip:<\/strong> For outdoor or marine use, a protective coating (Anodizing, Chem Film\/Alodine, or Paint) is mandatory to prevent stress-corrosion cracking.<\/p>\n<\/div>\n

Primary Applications<\/h3>\n

Aerospace & Aviation<\/strong>
\nThe primary alloy for aircraft wing structures, fuselages, and gears due to its immense strength comparable to some steels.<\/p>\n

High-Performance Sports Equipment<\/strong>
\nRock climbing carabiners, bicycle frames, and gears where weight reduction is critical but failure is not an option.<\/p>\n

Mold Making<\/strong>
\nUsed for prototype injection molds and blow molds. It is hard enough to withstand injection pressures but machines much faster than tool steel.<\/p>\n

Defense & Firearms<\/strong>
\nTactical receivers, buffer tubes, and precision optics mounts requiring rigidity and durability.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
