DURA-CORE® II 5056 Aluminum Honeycomb

Overview

For those designers demanding maximum mechanical strength with excellent corrosion resistance, DURA-CORE® II 5056 aluminum honeycomb is the lightweight material of choice.

Prior to bonding, the foil is cleaned and treated using a proprietary chemical conversion coating. The resulting honeycomb exhibits excellent corrosion resistance in hostile environments, especially salt fog. Typical weight loss after 30 days in salt fog (using ASTM B-117) is 15 mg/ft² (161.4 mg/m²), whileAMS-C-7438 allows up to 125 mg/ft² (1345.0 mg/m²).

We produce a broad range of cell sizes and densities, assuring that the correct product will be available for your application. When combined with our ability to custom-manufacture specific core types, plus our Special Processing capabilities, we can ship you drop-in core details in any shape, size, density or contour that you need.

For lightweight applications requiring maximum mechanical strength and excellent corrosion resistance at a good value, DURA-CORE® II 5056 is the best all-around structural core material.
