Material Matters

At Spectrographic as a metallurgical suppliers we offer re-calibration of Hardness Tester test blocks.  There are different types of hardness test reference blocks which relate to the testing for hardness.  These are Rockwell, Vickers, Micro Vickers, Knoop, Brinell and Leeb Test Blocks. The BS EN ISO 6507-3:2005 relates to metallic materials, Vickers hardness test and calibration of reference test blocks.  The extracted information of this standard Calibration of reference blocks appears in section 9 - Validity, it states: " The reference block is only valid for the scale for which it was calibrated. The calibration validity should be limited to a duration of 5 years.  Attention is drawn to the fact that, for Al- and Cu-alloys, the calibration validity could be reduced to 2-3 years". The question here is are all the test blocks valid that are currently been used for hardness testing within your metallurgy department.  This should become apparent...

Trying to find a pun to do with metals and E aster can be quite complicated, so I will try and give it a break, so we bid all those metalleggraphers a very Happy Easter. We are looking forward to the Easter B reak , which reminds me, our team of fixers are available to service and repair your old and tired equipment.   CAN WE FIX IT, YES WE CAN (no one called Bob actually works here, and in some cases we have to say sorry we Can't)   So, here's wishing you a really good Easter Holiday, lets hope for sunshine, and chocolate, although last time one of our engineers needed fixing due to sun stroke, but that seems like a long time ago! Easter Closure Thursday 24th March 2016  at 5pm u ntil 9am on Tuesday  29th March 2016. Except for me, the grumpy one, as I have decided to go play Golf on the Tuesday! But don't worry, the teams is in, to look after you. Email:  sales@spectrographic.co.uk Tel: 01274 966173 Website:  www.spectro...

Spectrographic have been refurbishing used hardness testers for the past 5 years.  These were an addition to our used metallurgical equipment range which include cutters, mounting presses, grinders and polishers. Recently we were asked by one our customers how to adjust a Rockwell hardness tester's  values, as we are so keen to help, we supplied them with a video to demonstrate how it should be done. Please find below our video of adjusting the values of the Rockwell hardness tester. Spectrographic hope that the information on how to do this operation with the hardness tester, was interesting to you. If you have any requirements for a used hardness tester, please contact the Spectrographic team. Email:  sales@spectrographic.co.uk Tel: 01274 966173 Website:  www.spectrographic.co.uk

This video shows the setting up of the Mitutoyo HV112 Vickers hardness tester, we look at un-packaging, taking care to remove the essential travel packaging and setting up and operating the hardness tester. We hope you enjoy watching the video, let us know if you have any question on all things Material Testing. Website - www.spectrographic.co.uk Email - sales@spectrographic.co.uk Phone - 01274 966173
