What is 1060 H24 Cast Aluminum Plate?
1060 H24 Cast Aluminum Plate is a commercial-grade aluminum alloy primarily composed of 99.6% pure aluminum, offering excellent corrosion resistance and workability. The "H24" designation indicates that it has been strain-hardened and partially annealed, providing a balance of strength and ductility. This material is commonly used in industrial applications such as sheet metal work, chemical equipment, and roofing. Its high thermal and electrical conductivity also makes it suitable for heat exchangers and electrical components. Due to its softness compared to other alloys, it is easy to form and weld.
What are the key mechanical properties of 1060 H24 Cast Aluminum Plate?
The tensile strength of 1060 H24 Cast Aluminum Plate typically ranges between 85-110 MPa, while its yield strength is around 75 MPa. It has an elongation rate of approximately 10-15%, making it moderately ductile. The material's hardness usually falls within the 25-35 HB range, indicating relatively soft characteristics. These properties make it ideal for applications requiring formability rather than high strength. Additionally, its lightweight nature (density ~2.7 g/cm³) contributes to its popularity in transportation and construction industries.
What are the primary applications of 1060 H24 Cast Aluminum Plate?
This aluminum plate is widely used in chemical storage tanks due to its excellent resistance to corrosive substances. It is also employed in architectural cladding, reflectors, and signage because of its smooth surface finish and reflectivity. The food industry utilizes it for processing equipment as it does not react with organic compounds. Additionally, it serves as a material for electrical busbars and heat sinks due to its high conductivity. Its malleability allows for deep drawing and spinning applications in manufacturing.
How does 1060 H24 compare to other aluminum alloys like 3003 or 5052?
Unlike 3003 (which contains manganese for added strength) or 5052 (magnesium-chromium alloy for higher durability), 1060 is nearly pure aluminum, making it softer and less strong. However, it offers superior electrical and thermal conductivity compared to these alloys. While 3003 and 5052 are better for structural applications, 1060 excels in environments requiring corrosion resistance and formability. Cost-wise, 1060 is generally more economical due to its simpler composition. Its weldability is also better than that of many alloyed alternatives.
What are the welding and machining considerations for 1060 H24 Cast Aluminum Plate?
Welding 1060 H24 is relatively straightforward using TIG or MIG methods, but filler rods like 1100 are recommended for optimal compatibility. Since the material is soft, machining requires sharp tools and moderate speeds to avoid excessive burring. Lubrication is advisable during drilling or milling to prevent material adhesion. Unlike harder alloys, 1060 does not require pre-heating for most fabrication processes. Post-weld annealing may be necessary if work hardening occurs during forming operations.
