Fasteners – such as nuts, bolts, screws and rivets – are essential structural components of vehicles, and their failure can have severe repercussions for driver safety. Many of these metallic items are also unavoidably exposed to harsh operating conditions, meaning they are liable to corrode over time.

X-ray fluorescence (XRF) spectrometry is a useful technology to measure the thickness of metal layers. Handheld XRF is an indispensable tool in quality assurance.

Handheld X-Ray Fluorescence (HHXRF) analyzers verify materials quickly, reliably and cost-efficiently. They can identify a material’s elemental makeup within seconds, making it easier for manufacturers to select the right metal grades and tolerances for their needs. 

With the increasing regulations in safety, reliability, traceability, and regulatory compliance, material verification has become an essential component in a safety and reliability program.

When we talk to customers who are interested in learning more about XRF, there are some questions that we answer all the time. Check out some of the most frequently asked questions and their answers below.

Electroless nickel (EN) is industry’s most common plated finish. It’s widely used for applications that demand wear resistance, hardness and corrosion protection—particularly if parts have complex geometries. It is also used in PCB manufacturing within a process known as ENIG, electroless nickel immersion gold. 

X-Ray Fluorescence analysis plays an important role in protecting consumers by detecting possible toxic heavy metals in electronics, automobiles and medical devices before they make it to market.

X-ray fluorescence is an elemental analysis tool that has been a mainstay of test labs for decades. A versatile NDT method that demands only minimal sample prep and can be run by novice operators, it is perhaps most valued for delivering accurate results quickly. Today, evolving XRF capabilities are moving this quality assurance workhorse into critical new roles in a widening spectrum of industries.

Scientists use non-invasive techniques to trace five sculptures to foundry in WWII Paris.

Before selecting an X-ray fluorescence (XRF) analyzer, consider what you want to achieve. For example, if you are looking to confirm alloy grades for incoming goods QC, you will want to know what the important element in those grades should be.
