McKechnie and Omega Closed as a result of the NZ Govt Covid19 decision to move the country to Level 4 status.

We will reopen on April 23rd, 2020

As most of you will be aware the New Zealand Government moved the country to a Level 3 crisis status on Monday March 23rd and to Level 4 at midnight on Wednesday 25th March 2020.

This means that along with most businesses, we will be closing down from 2.30 pm on Wednesday 25th of March, 2020 for a period of four weeks. At this stage we will look to re-open on Thursday the 23rd of April 2020.

Temper Designations

F
As extruded only.

T1
Solution treated and quenched from an elevated temperature as part of the extrusion process and naturally aged.

T4
Solution treated and quenched from an elevated temperature as part of the extrusion process and naturally aged. Applies to products that are not cold worked, or where the effect of cold work is not recognised in applicable standards.

T5
Solution treated, cooled from an elevated temperature as part of the extrusion process and then artificially aged to substantially improve mechanical properties.

T52
A temper satisfying T5 requirements with improved formability.

T6
Solution treated, cooled from an elevated temperature as part of the extrusion process and then artificially aged to give maximum mechanical properties.

T8
Solution treated, cooled from an elevated temperature as part of the extrusion process, cold worked and then artificially aged. Applies to tube and wire products.

Note: A second or third digit maybe added to designated tempers. This indicates a variation in the production process has been applied to alter the final characteristic of the product, i.e. to achieve improved ductility etc
