The production of metal alloy parts is increasing being done using additive manufacturing (3D printing) processes. 3D metal printers use a metal alloy powder that is fused by a laser in depositional layers 30-50µm thick. The part is thus progressively built up layer by layer until the desired form is completed. This technology is now commonly being applied to the production of mission critical components in the aerospace medical industries. Verifying the quality of the powder material is an important quality control step in the process. Our certified reference materials can assist with that process.
In July LGC ARMI received its official accreditation to ISO 17034 for reference material production and ISO 17043 for proficiency testing. We are very proud of this achievement as these accreditations represent the gold standard in reference material production and proficiency testing.
ARMI introduces two new certified reference materials for nickel alloys. IARM-Ni214-18 is a Haynes® 214® alloy and IARM-NiB3-18, a Hastelloy® B3® alloy.
ARMI introduces two new certified reference materials Waspaloy® and Alloy X, IARM- NiWasp-18 and IARM-NiX-18.
ARMI introduces three new certified reference materials for Inconel 690, Haynes® 282® and Incoloy 25-6Mo.
Finding Reference materials for some grades of Titanium and Nickel Alloys can be challenging. ARMI is always seeking to support the needs of analytical laboratories working with metal alloys.
“Finally, we have a ‘fracking’ standard for MEEP analysis!”
Cobalt alloys are commonly used in applications requiring high strength, high temperature corrosion and wear resistance. Despite their wide use there are relatively few reference materials for this important alloy group.
ARMI is pleased to introduce 2 new certified reference materials for cobalt alloys: IARM-Co6B-18 a Stellite 6b alloy and IARM-CoElgiloy-18 an Eligiloy® alloy. You can download the certificates of analysis on our new product page. These products are available in three forms; 38mm diameter x 3mm thick disks for XRF, 38mm diameter x 19mm thick disks for optical emission and chips for ICP-OES/MS and AA.

One of the most common ways to weld cast iron is by stick or arc welding. The stick is an electrode covered with flux or filler material. The most common filler material for welding cast iron are nickel alloys. The chemical composition of the filler material can impact the quality of the weld so it is important to have reference materials to verify the composition. Reliance Foundry provides a very good discussion of the procedures for welding cast iron in their blog post “How to Weld Cast Iron”.
There are few reference materials available for verifying the chemical composition of welding fillers so we decided create one in collaboration with Special Metals. This new reference material called IARM-Ni244H-18 and is based on a is a nickel-iron-manganese alloy that is used as welding filler material and sold under the commercial name of NI-ROD® 44 Filler Metal.
The IARM Ni244H-18 has 22 major and minor elements certified as well as informational values for an additional 55 trace elements. The unique major element composition of this alloy (41.1% Ni, 39.9% Fe, 10.9% Mn and 6.9% Cr) make it extremely useful as a sample to extend the calibration ranges for XRF and OE applications as well as a calibration monitor sample.
This reference material is available as 38mm x 3mm disks for XRF, 38mm x 19mm disks for OE or as chips for ICP-OES and ICP-MS applications. The certificate of analysis for this reference material available for download on our new product page.
Have you seen those YouTube videos showing folks lighting their water on fire as it cascades into the bathroom sink? Pretty scary, huh? In some parts of the world, including the US, people have unknowingly built their homes over large deposits of natural gas. Most of this gas is trapped in layers of shale deep beneath the aquifers that supply their household water.
Hydraulic fracturing or “fracking” is a process used to remove the natural gas from the shale layer, harvesting the gas and making it available for the natural gas market. The big question is how did the natural gas get into the household water?
