U
*For unfinished extrusions with cut lengths other than half bar, the finish designation is a U.
**If the part is less than 10 inches, the first of these 5 digits (digit 7 of the 13 digit series) would be a zero (0).
Examples:
If you wanted to simply order extrusion # 78020 in standard bar form, the part number would be: 780201F00000. The unit price
would be sold by the foot.
If you wanted extrusion 78020 cut to a length of 6.500" and black anodized, the part number would be: 780203B06500G. The
unit price would be by the piece.
If you wanted extrusion 78020 cut to a length of 14.725" and a wash finish, the part number would be: 780203U14725G. The unit
price would be by the piece.
If you wanted extrusion 78020 cut to a length of 14.725" and Gold Chromate finish, the part number would be: 780203C14725.
The unit price would be by the piece.
Standard Aavid Thermalloy parts require all 12-13 positions to be complete.
Non-Standard Extrusions
Aavid Thermalloy has over 10,000 extrusion profile designs on file, most with the extrusion die already available. These
parts have minimum order requirements and longer lead times, but may be cost effective compared to a new design.
Customizing & Advanced Capabilities
We offer several options for those applications which require a more unique solution. Challenge us with your thermal
requirements - we can design custom solutions.
