Metallurgy is one of the most important fields in the world. Thanks to it, there is a huge array of alloys of various metals to use. They can have the specific properties to suit all kinds of needs. However, with so many options it can be tricky to identify which is which. Luckily, we can help. Format NDT Ltd can offer reliable PMI testing that checks metals against the latest databases to identify them.
One metal and its alloys we can help you to identify is nickel. It is a versatile material that is perfect for an array of industrial applications. The pure form is popular but you can also find it in alloys with iron, copper, molybdenum, chromium, titanium, and more. Nickel is an alloying element in other materials too but is not the primary element.
People like to use nickel and its alloys for a number of applications because of the impressive attributes it offers. That can include high corrosion resistance, excellent performance at high temperatures, and a low rate of thermal expansion. The levels of each can vary greatly though, that is why you need to ensure you identify the exact alloy you have.
Some notable alloys
Nickel iron alloys are some of the most popular because of the very low thermal expansion. Some can exhibit just a tenth of the expansion of carbon steel. This gives them really good stability. Specific ones to look at here include alloy 400 and FeNi36.
Nickel-copper is a common material in the marine industry. It has very high corrosion resistance, especially to salt water. Notable alloys here include MONEL alloy 400 and MONEL alloy K-500.
If the project requires high chemical resistance, nickel molybdenum alloys are a good choice. They have exceptional resistance to acids. A few of the best options include Ni84Mo16 and Ni80Mo20.
One of the most interesting alloys is nickel titanium. They have a great ability to retain shape memory. What this means is you can form a product at a high temperature and then deform it at a lower one. The item will remember the initial form and return to it if heated again. Popular alloys include 55% Ni and 45% Ti.
Choose PMI testing
Format NDT Ltd is a company that understands how vital it is to use the right alloys. We have seen several companies struggle because they had specific performance parameters in mind but chose an alloy that was not suited to them. This can lead to big issues.
Our PMI testing service is a way to rapidly identify alloys of many metals, including nickel. The equipment we use has access to the latest databases to ensure new materials get added regularly. This means we remain up to data and able to provide a great service.
So, if you need to identify a metal, please speak to us. We work across the UK and set very high standards. The testing is non-destructive and can provide a quick result.
