Aluminum 5052-H32

Aluminum 5052-H32 is the highest strength alloy of the non-heat-treatable grades. Its primary alloying element is Magnesium, which gives it superb corrosion resistance, particularly against saltwater and industrial atmospheres. While it is softer and more difficult to machine than 6061 due to its gummy nature, Jucheng Precision has optimized cutting strategies to handle 5052 effectively. The "H32" temper indicates it has been strain-hardened and stabilized. It is the go-to material for sheet metal work, welded assemblies, and marine components where failure from vibration or corrosion is a concern.

5052-H32 Machining Capabilities

Capability	Technical Description	Jucheng Advantage
Marine Grade Machining	Processing 5052 components specifically for saltwater environments where 6061 would corrode.	We produce corrosion-resistant fittings and flanges for marine electronics and boat hardware without needing plating.
High-Quality Welding	5052 offers superior weldability compared to other alloys. We machine parts ready for TIG welding.	Ideal for fuel tanks and sealed enclosures. Our machining ensures perfect fit-up for strong, leak-proof welds.
Sheet Metal Fabrication	While we CNC machine 5052, it is also the best alloy for bending and forming.	We can machine precise features (holes/slots) into 5052 plates before they are bent into chassis, ensuring tight tolerances.
Surface Finishing	5052 anodizes well, producing a clear, bright finish (unlike the yellowish tint of 7075).	Excellent for cosmetic parts like street signs or architectural panels exposed to weather.

Fabrication Guidelines for 5052 Aluminum

Machinability Note:
5052 is softer and “gummier” than 6061-T6. It produces continuous, stringy chips. Tip: We use high-rake tools, high speeds, and plenty of coolant to prevent material buildup on the cutting edge (BUE).

Non-Heat Treatable:
Unlike 6061 or 7075, 5052 cannot be heat treated to increase hardness. It is strengthened only by work hardening (H32 temper). Do not specify T6 heat treatment for this alloy.

Bending:
5052 has excellent formability. It can be bent to a tight radius without cracking, making it the preferred choice for stamped or formed sheet metal parts.

Primary Applications

Marine Hardware
Boat fittings, fuel tanks, and hulls. Its high Magnesium content provides exceptional resistance to saltwater corrosion.

Transportation
Bus and truck bodies, fuel lines, and traffic signs due to its high fatigue strength and vibration resistance.

Electronic Chassis
Sheet metal enclosures, mounting brackets, and panels that require extensive bending and forming.

Consumer Appliances
Kitchen equipment panels, refrigerator liners, and fan blades where corrosion resistance and formability are key.
