Hammond 1590BSCB Cobalt Blue Diecast Aluminum Enclosure - Rugged Case

Our review of the Hammond 1590BSCB finds it best suited for hobbyists, instrument builders, and small electronics projects that need a durable, easy-to-machine case. The single biggest reason to buy is its rugged diecast aluminum alloy construction, which combines toughness with improved EMI/RFI shielding and a professional painted finish. Screws are included and the lid secures in countersunk, pre-tapped holes, making assembly straightforward for anyone mounting PCBs, switches, or connectors in a compact footprint.

Key Features

• Rugged construction: Diecast aluminum alloy provides strong mechanical protection while remaining simple to machine for custom cutouts and mounting.
• Shielding: Lap joint construction and metal body provide improved EMI/RFI shielding for sensitive electronics.
• Compact size: The B size measures 4.39 in x 2.37 in x 1.50 in (112 x 60 x 38 mm), suitable for small pedals, controllers, and sensor enclosures.
• Ingress protection: Designed to meet IP54 for dust and splash resistance and can reach IP66 when used with an optional gasket for harsher environments.
• Painted finish: Cobalt Blue (RAL 5013) provides a durable factory color that looks professional on finished projects.
• Simple assembly: Lid secures with included screws into pre-tapped holes for reliable closure and repeatable access.

Who It's For

This enclosure is ideal for DIY electronics builders, pedalmakers, and engineers needing a small, sturdy case with good shielding and a ready-made finish. Its easy-to-machine alloy suits custom panel work, and the included screws make it convenient for prototypes and small production runs.

Those who need very large enclosures, ultra-resistant paint for constant rough handling, or integrated mounting hardware should look elsewhere; this product is focused on compact protection and shielding rather than oversized capacity or specialized internal racks.

Pros & Cons

Pros

• Solid, high-quality diecast body that is easy to drill and machine for custom projects.
• Good EMI/RFI shielding thanks to lap joint design and metal construction.

• Attractive Cobalt Blue finish that presents professionally on finished builds.

Cons

• Paint scratch resistance has been noted by some users, so extra care during drilling and handling is advisable.
• Size may be smaller than expected for some projects, so check dimensions before ordering.
