Metals & Alloys

Full-Service Metal and Alloy Testing Lab

Metal Testing and Alloy Testing are specialties of Laboratory Testing Inc. and the foundation of the company founded in 1984. We test and analyze all types of ferrous and nonferrous metals and alloys, including precious metals and powdered metals. All services are performed at our one-stop facility near Philadelphia, PA (USA).

Test to Ensure Quality and Performance

LTI measures the quality and performance levels of raw materials and product samples according to industry standards, 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 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 also risen steeply, and are still the mainstay of manufacturing. In addition, the safety and reliability requirements for these products have also increased.

Support Business Decisions with Metal Testing

With over 30 years of experience, the information provided by LTI’s wide-range of metal testing services has proven valuable to customers in all aspects of basic metals, fabricated metal products and manufacturing. Our testing services support a wide-range of business types, including mining, foundries, tubing, pipe, bar and plate production, casting, forging and stamping, forming of component parts and finished products, heat treaters and welders.

LTI provides services for the following and more:

  • Treatments alter the microstructure of metals and alloys, and thereby influence their properties such as yield strength, ductility, fracture toughness and others. Testing mechanical properties and examining the microstructure often follow treatments to verify that the expected results have been achieved. LTI has furnaces that are used in performing capability heat treating and testing of specimens.
  • 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.
