FAQ Section
What is the weight of a 1/4 inch aluminum plate?
A 1/4 inch aluminum plate weighs approximately 3.6 pounds per square foot, making it substantially lighter than steel while maintaining good structural integrity.
Can 1/4 inch aluminum plate be welded?
Yes, 1/4 inch aluminum plate can be welded using appropriate techniques. MIG and TIG welding are commonly used, with proper preparation and the right filler materials being essential for strong, clean welds.
How does 1/4 inch aluminum plate compare to steel?
While steel offers higher strength, aluminum provides better corrosion resistance, lighter weight, and easier machinability. The choice depends on specific application requirements and environmental conditions.
What surface finishes are available?
Common finishes include mill finish, brushed, polished, anodized, and painted surfaces. The choice depends on aesthetic requirements and environmental exposure conditions.
Is 1/4 inch aluminum plate suitable for outdoor use?
Yes, aluminum naturally forms a protective oxide layer that makes it highly resistant to atmospheric corrosion. For harsh marine environments, specific marine-grade alloys like 5052 or 5086 are recommended.
How should I cut 1/4 inch aluminum plate?
Use carbide-tipped blades for sawing, plasma cutting for complex shapes, or waterjet cutting for precision work. Always use appropriate safety equipment and proper cutting techniques.
Can aluminum plates be bent or formed?
Yes, 1/4 inch aluminum plate can be formed and bent using proper equipment. The bend radius depends on the specific alloy and temper, with softer tempers allowing tighter bends.
