Engineering Properties of 5052-H32
Alloyed with 2.2–2.8% magnesium and 0.15–0.35% chromium, 5052-H32 maintains superior durability in marine environments and aggressive industrial atmospheres.
CNC Machining & Burr Prevention
Cutting Speed (Vc): 300 – 600 m/min with flood coolant.
Challenge: 5052 is softer and more ductile than 6061, which can lead to built-up edge (BUE) and gummy burr formation on exit edges.
Solution: Utilize razor-sharp, high positive rake angle carbide cutters with high-pressure coolant blast to clear chips instantly.
Frequently Asked Questions
How do you avoid burrs when milling 5052 aluminum?
Use high rake angles (15°–20°), sharp uncoated or ZrN-coated carbide tools, and climb milling toolpaths to ensure clean chip shear.
Can 5052 aluminum be heat treated to increase hardness?
No, 5052 is a non-heat-treatable alloy; its strength is achieved exclusively through cold working (strain hardening).
