Shot Peening Naval TV Almag Antenna Flanges

• Shot peening is a cold working process in which the surface of the Almag Flange is bombarded with small spherical media called shot.
• Each piece of shot striking the surface creates a small indentation or dimple.
• Overlapping dimples develop an even layer of metal in residual compressive stress.
• Fatigue cracks will not start or propagate in a compressively stressed zone.
• When a residual compressive stress is produced in the surface, the tensile stress created by the applied load must first overcome the residual compressive stress before the resultant surface stress becomes tensile.

• Almag is a marine grade aluminum alloy that will not corrode and has a high tensile strength and we have many antennas still in opeation at 20 years. We use Stainless Steel mounting screws which are protected from galling through electrolysis via dissimilar metals with Tef-Gel.
• Works wonders for many years. This a Telflon suspended jell impervious to detergents etc.
• ALMAG Aluminum alloy 535.0 is an aluminum magnesium alloy that does not require heat treatment to reach full properties.
• Almag has excellent corrosion resistance and machining characteristics.

All of our Flanges and Antennas are made in the State of Florida USA
