Metal material testing items

Metal materials are very popular in China because they can be flexibly applied in various fields, and the scope of their application is expanding increasingly. People's daily lives are gradually becoming inseparable from the products made of these materials, and the development potential is huge! 

Let's get straight to the point. Today, we will introduce to you all the relevant knowledge about the performance testing and certification of metal materials! 

I. Detectable Metals: 

Carbon steel/low alloy steel, stainless steel, cast iron, non-ferrous metals (copper, aluminum, magnesium, tin, titanium, etc.), welding materials, high-temperature metal materials, other metal materials, mechanical equipment components, metal components in manufacturing processes, etc. 

II. Main Analysis Categories: 

Qualitative analysis: Determine the main components of an unknown metal material and identify its composition. 

Quantitative analysis: Conduct quantitative analysis on the corresponding material grades or the required metallic materials according to the standards, to determine whether they meet the specified requirements or standards. 

III. Main Projects: 

1. Stainless steel grade identification: 304, 304L, 316 and other types of stainless steel; Element content detection: Nickel Ni, Chromium Cr, Molybdenum Mo, Iron Fe, etc. 

2. Alloy composition analysis: Copper alloys, aluminum alloys, zinc alloys, solder, and other alloys: Carbon C, Nitrogen N, Sulfur S, Phosphorus P, Silicon Si, Copper Cu, Iron Fe, Aluminum Al, Tin Sn, Molybdenum Mo, Nickel Ni, Chromium Cr, Manganese Mn, Titanium Ti, Tungsten W, Lead Pb, Zinc Zn; 

3. Element Analysis: Oxygen, Nitrogen and Hydrogen Gas Element Detection, Precious Metal Detection, Heavy Metal Detection, RoHS Compliance Testing
