100% of the production is controlled by automated ultrasonic inspection
|
Example of a rejected ingot
High level of ultrasonic indications
= High level of arcing during sputtering | 
Ultra clean Al 0,5% Cu PHP alloy
Low level of ultrasonic indications
= No arcing |
- For many different applications in the high purity field,
PHP must guarantee that material is "defect free".
This is especially important when trying to improve
the yield of sputtered products which is directly related
to defects within the raw material.
- PPechiney High Purity has greatly improved its elaboration and casting processes in order to deliver cleaner products to the targets manufacturers.
