FORD WSD-M1A337-A5

Description / Abstract: FORD WSD-M1A337-A5, 2000 - STEEL SHEET, LAMINATED SOUND/VIBRATION DAMPING ***TO BE USED WITH FORD WSS-M99P1111-A***

The materials defined by these specifications are formable, weldable multilayer composites for use in applications where sound reduction is required. These materials consist of a viscoelastic polymer material sandwiched between sheets of drawing quality steel meeting the requirements of WSD-M1A333-A2/A3. For variant A5 the steel has a two sided aluminum alloy coating for enhanced higher temperature performance, meeting requirements of WSD-M1A295-A1/A2/A3. The grades have optimized damping loss factors η of> 0.1 for the following ranges of temperature:
