Our Customers Say:

“I had an urgent request today for hardness testing to be performed by an independent lab to support our own testing for our customer and the end user. Your team was very accommodating as we received the results prior to a critical meeting. I greatly appreciate LTI’s efforts for the rapid turnaround!”

Tim Steber,
Regional Sales Manager

Metals & Alloys

Full-Service Metal and Alloy Testing Lab

The use of metals and alloys like cast iron, steel, stainless steel and alloy steel has been a part of our human history for ages. In recent years, even though the demand for nonferrous metals and new non-metallic materials has increased dramatically, world metal and alloy production and use have risen steeply as well, and are still the mainstay of manufacturing.

Along with the dramatic rise in usage, the safety and reliability requirements for these products have also increased. Laboratory Testing Inc. can test and analyze all types of ferrous and nonferrous metals including precious metals, alloys and ferroalloys, and powdered metals. With almost 30 years of experience, LTI can measure the quality and performance levels of your raw materials or product samples according to industry standards and specifications, and customer requirements. If your material or product fails to perform as expected, our laboratory technicians and materials engineers are highly qualified to carry out a wide-range of metal testing and evaluation to help identify the root cause.

The information provided by LTI’s wide-range of testing services has proven valuable to customers in all aspects of basic metals and fabricated metal product manufacturing including mining, foundries, tube, pipe, bar and plate production, casting, forging and stamping, forming of component parts and finished products, coating and heat treatments and welding:

  • Some manufacturing treatments and processes can modify or alter the microstructure of metals and alloys, and thereby influence their properties such as yield strength, ductility, fracture toughness and others. These properties need to be considered, and often tested, by purchasers that will further process these products.
  • The composition and corrosion susceptibility of metals may be determined to aid in material selection.
  • Surface or internal flaws, inconsistencies and discontinuities that occur in basic metals or a component product during manufacturing can be uncovered by various types of testing before problems or failures occur.

Calibration services are also provided for the “one-stop” convenience of our customers in manufacturing and other industries that rely on accurate gages, measuring hand tools, or measuring instruments (pressure, torque, force, electrical, temperature, mass, vacuum). On-site calibration is also available for equipment such as surface plates, optical comparators, ovens and furnaces, hardness testers, scales and balances, temperature controllers and more.
