7050-T7451 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
Thick Section Machining<\/strong><\/td>\n7050 maintains its strength even in very thick sections (>150mm), unlike 7075. We machine deep pockets from solid billets.<\/td>\nOur rigid gantry mills can remove massive amounts of material from thick 7050 blocks while maintaining dimensional stability.<\/td>\n<\/tr>\n
High Fracture Toughness<\/strong><\/td>\nMachining critical safety parts that require resistance to crack propagation.<\/td>\nWe use specialized cutting parameters to avoid inducing surface stress, ensuring the part’s fatigue life is not compromised.<\/td>\n<\/tr>\n
Deep Pocketing<\/strong><\/td>\nMilling deep, thin-walled ribs in structural bulkheads.<\/td>\nAdvanced chip evacuation strategies prevent chip re-cutting, ensuring a smooth finish at the bottom of deep pockets.<\/td>\n<\/tr>\n
Stress-Relieved (T7451)<\/strong><\/td>\nThe T7451 temper is over-aged and stretched to minimize internal stress.<\/td>\nResulting parts have minimal distortion after machining, essential for large precision aerospace frames.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Fabrication Guidelines for 7050 Aluminum<\/h3>\n

7075 Replacement:<\/strong>
\n7050 is often chosen over 7075 for thick plates (over 3 inches)<\/strong> because 7075 loses strength in the center of thick sections, whereas 7050 retains it. Tip:<\/strong> Specify 7050 for heavy-duty structural blocks.<\/p>\n

Corrosion Resistance:<\/strong>
\n7050-T7451 offers significantly better Stress Corrosion Cracking (SCC)<\/strong> resistance than 7075-T6. Tip:<\/strong> Ideal for parts under constant tensile stress in corrosive environments.<\/p>\n

Weldability:<\/strong>
\nLike 7075, 7050 is not weldable<\/strong>. It relies on its high material strength and machining from solid blocks to create complex unitary structures.<\/p>\n<\/div>\n

<\/p>\n

\n

Primary Applications<\/h3>\n

Commercial Aviation<\/strong>
\nFuselage frames, wing skins, and bulkheads requiring high strength and fracture toughness.<\/p>\n

Military Aircraft<\/strong>
\nHeavy-duty structural components for fighter jets where performance under extreme load is critical.<\/p>\n

Aerospace Fittings<\/strong>
\nThick attachment fittings and landing gear components that must resist stress corrosion.<\/p>\n

Heavy Structural Blocks<\/strong>
\nAny application requiring a large, solid chunk of high-strength aluminum.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
