Metallurgy consumables range åtto abrasives
Atto metallurgy consumables play a key part in metallurgical sampling. Metallurgical Sampling is a key part of Metallography and metal testing. Metallography is the study of the microstructure of metals. Metallography is used to determine if the material has been properly prepared and is of a reliable structure. This is essential in todays fast changing industries with everchanging metallic materials being used.
The finished material can be affected by different factors ranging from alloy composition to processing conditions such as; cold working, heat treatment, and welding. Therefore for industries such as aerospace & automotive it is essential to test the quality of metal materials being used.
When testing metals, a sample is taken from the metal being tested, this refers to the metallurgical sampling. When doing this, it is important to use the correct cutting wheel (metallurgy consumable) for the material being tested. Choosing a metallurgical sampling wheel involves considering factors such as surface speed (SFM) for a given wheel diameter and the type of cooling system employed.
However, the primary factor is the hardness of the material being cut. There are several different hardness charts which you may use. We use the Vickers Hardness HV scale, but you can easily find conversion charts.
By selecting the correct wheel to match the material being tested you avoid making any changes to the metallurgical sample. Using the incorrect metallurgical cutting wheel can lead to burning or altering of the material before tests are carried out.
At åtto Abrasives we have developed our range of resinoid and rubber bonded precision cut-off wheels to match all types of metallic metals. These include metallurgical sampling cut-off wheels for ferrous & non ferrous metals as well as hard and soft metals.
The åtto Abrasives metallurgial sampling range can be matched to the specific material that you are testing. Four Specifications each matching a
specific range of material hardnesses are available here.
N – Soft Ferrous Metals 0 – 300 (HV)
M – Medium Ferrous Metals 300 – 500 (HV)
L – Hard Ferrous Metals 500+ (HV)
Q – Non-Ferrous 0 – 300(HV)
These will provide a burr-free high precision cut. While they will also generate little to no heat. The åtto abrasives range is available in a wide range of sizes depending on your requirements.
