Machining Allowances
All Kormax AB2 Nickel Aluminium Bronze bar has machining allowances added to the sizes quoted. To use 4-1/2″ x 2-1/2″ hollow bar as an example, this material would measure approximately 4.620″ to 4.660″ OD x 2.346″ to 2.392″ ID as supplied (see table below). Therefore, this allows finished components measuring 4-1/2″ OD x 2-1/2″ ID to be easily manufactured from 4-1/2″ x 2-1/2″ hollow bar.
Size Range | OD Allowance | ID Allowance |
up to 3″ | +0.053″ to +0.073″ | -0.108″ to -0.154″ |
3-1/4″ to 4″ | +0.079″ to +0.109″ | -0.108″ to -0.174″ |
4-1/4″ to 5-1/2″ | +0.120″ to +0.160″ | -0.125″ to -0.221″ |
5-3/4″ to 6-1/4″ | +0.163″ to +0.214″ | -0.135″ to -0.231″ |
6-1/2″ to 10″ | +0.180″ to +0.230″ | -0.190″ to -0.286″ |
Above 10″ | +0.125″ | -0.125″ |
