Value Collection 91090456 Aluminum Sheet Alloy 5086

Product Description

The VALUE COLLECTION 91090456 is a flat aluminum sheet cut to 24 inches by 24 inches with a nominal thickness of 0.25 inches, produced in Alloy 5086. Alloy 5086 is a non-heat-treatable aluminum-magnesium alloy recognized for strong corrosion resistance, particularly in marine and saltwater environments, and for good weldability. At 14 pounds per sheet, this piece suits structural fabrication, panel work, repair applications, and general-purpose metalworking tasks. HVAC fabricators, plumbers, electricians, and sheet metal contractors use flat aluminum stock for duct transitions, mounting plates, enclosure panels, and custom brackets.

This sheet is appropriate for light structural and architectural fabrication in both residential and commercial settings. Its 5086 alloy designation makes it well suited for coastal or high-humidity installations where corrosion resistance is a priority. Typical applications include marine vessel components, equipment enclosures, ventilation panels, and utility mounting surfaces. Fabricators working in HVAC, refrigeration, and general mechanical trades will find this stock useful for custom-cut parts and field repairs requiring a durable, weldable aluminum substrate.

Key Features

• Alloy 5086 aluminum-magnesium composition provides excellent corrosion resistance in marine and high-humidity environments
• Full 24 x 24 inch flat sheet requires no initial shearing for square applications
• 0.25 inch nominal thickness suitable for structural panel and bracket fabrication
• Weldable alloy compatible with standard MIG and TIG aluminum welding procedures
• Sheet weight of 14 pounds supports predictable handling and freight planning

Compatibility

Designed as a general-purpose flat aluminum sheet for fabrication, repair, and custom metalwork applications across HVAC, plumbing, marine, and structural trades.

Installation Notes

Sheet metal work on this stock is typically performed by licensed sheet metal workers, HVAC technicians, or general fabricators using shears, nibblers, angle grinders, or circular saws fitted with non-ferrous cutting blades. Wear appropriate cut-resistant gloves and eye protection when cutting or deburring edges. When welding Alloy 5086, follow the material manufacturer guidance for filler selection and preheat requirements. Verify local codes such as SMACNA standards for duct fabrication or applicable building codes for structural panel applications before installation.
