Zero is the leading manufacturer of quality, deep-drawn aluminum and plastic cases and enclosures. We offerover 32,000 pre-tooled sizes and can develop any custom design according to your specifications. Zero is the only case manufacturer to offer full in-house modification services - eliminating the need for multiple vendors when ful- filling alteration, assembly, accessory and cosmetic requirements. Deep draw is the process of gripping a sheet of aluminum (or brass, copper, cold rolled steel or mu metal)between a pressure pad and a draw ring. Hundreds of tons of pressure is then exerted onto...

High Strength-to-Weight Ratio Aluminum alloys are known for their strength and light weight, especially when heat-treated to T6 condition. Extraordinary Resistance to Corrosion Aluminum is highly resistant to nearly all substances that cause corrosion and weathering. Endurance Against Stress, Tearing and Cracking Aluminum offers a much better fracture toughness than most other materials used in enclosures, including resis- tance to breakage and fractures. Sustaining Cold Temperatures Instead of becoming more fragile and brittle in cold weather, the tensile strength of aluminum actually increases,...

CAUTION: Pattern AA Nutplate patterns arerestricted to minimum sizes due to space on basic enclosures as fol- lows: Recommended for boxes under 1.62Ք wide > Pattern BB Not recommended for boxes under 1.75 x 2.87Ԕ Pattern CC Not recommended for boxes under2.00 x 2.50Ԕ Pattern DD Not recommended for boxes under 1.44 x 2.44Ԕ Pattern EE Not recommended for boxes under 1.75 x 2.87Ԕ Pattern FF Not recommended for boxes under 2.00 x 3.00Ԕ Pattern GG Not recommended for boxes under 1.75 x 3.75Ԕ Pattern HH Not recommended for boxes under 2.12 x 3.00Ԕ Pattern JJ Not recommended for boxes under 2.00 x 4.00Ԕ...

On all boxes under 1.62width use pattern AA only. 49 > NOTE: All nutplates are located oncenter lines or located .25Ԕ from radii points of tangency with the exception of pattern HH and JJ. The typical location of HH and JJ is as shown in pattern HH. >

Alloy: An aluminum alloy is a metal that is a mixture of aluminum and one or more other elements. 1100: 99% pure aluminum. 3003: Aluminum/manganese alloy. 6061: Aluminum/manganese/silicon alloy. Artificial Aging: Anodizing: Electrochemically converting the surface of aluminum from metallic aluminum to aluminum oxide (alumina) by making aluminum the anode in a plating-type electrochemical cell. It is used not only for added protection, but also in conjunction with dying and sealing to create decorative effects. Speeding up the natural aging cycle by heating the metal for a short time. CF: Flush...

Reflectivity: RFI: Radio frequency interference. The ability of a surface to mirror or reflect radiant energy. The reflectance of aluminum is exceptionally high. Seamless Construction: An exceptional attribute of deep drawn shells. Deep drawn shells haveno seam. Solution Heat Treating: A strengthening thermal treatment in which certain aluminum alloys areheated to a relatively high temperature and then held (soaked) for varying times. A rapid quench or natural aging follows the heating period. Strain Harden: Secondary Aluminum: Tempering through strain. Same as work harden. Metal recovered aluminum...
