Alloys and semi-finished products

We control the complete process chain for manufacturing your SMA components and systems. From melt metallurgy, through various semi-finished products and forming methods to your specifically designed and configured products. This allows you to profit from an enormous bandwidth of possibilities: Because with our freedom to make adjustments at every point of the process chain, you will receive unique SMA components specifically tailored for you. Therefore you can ensure that your product or system will exactly perform the task it is supposed to when you install it in your destined area of application. This has proven to be a key reason for the success of our customers.

Alloys (melt metallurgy)

Melt metallurgy forms the basis for your solution. This is where we produce individual alloys according to your requirements. You can profit from a wide variety of alloys based on nickel and titanium. In their most relevant properties, alloys based on NiTi usually exhibit significantly superior parameters to other SMA. For adding further elements to the alloy, usually you will resort to Cu, Fe, Cr, V, Hf, Nb, Co, Mo, Zr, Pt or Pd. Your choice within our portfolio therefore allows you to choose among binary, ternary, quaternary and higher-grade SMA alloys:

Your custom alloy

On the market you will merely encounter few available standard alloys. However, when choosing your alloy, you should also consider the individual characteristics of shape memory alloys that may become relevant in your application; in particular their mechanical properties and switching temperatures. You will find that the market does not offer you enough flexibility because the few standard alloys available on the market don’t cover this required bandwidth.

At Ingpuls however, you will receive custom alloys which are designed exactly for your requirements. This allows you to profit from significantly superior alloys which have been designed or adapted for your application in order to achieve your exact requirements. These will prove many times superior to conventionally available standard alloys since they are much closer to the ideal alloy.

Identifying your requirements / confidentiality

Already during alloy development or selection, it is essential to understand the necessary properties of your subsequent application. In order to achieve this, the mutual exchange of information in a structured manner has proven beneficial. Thereby, our customers usually wish to work under a non-disclosure conditions: This type of agreement can be established with us in advance and then serves to provide mutual protection of the respective know-how.

For documenting and forwarding your requirements, please make use our standardised query process. This ensures that:

  • you will significantly reduce the response time to your inquiry
  • you will receive a qualified answer in all cases: Even if it turns out that your requirements may not be ideally met by using SMA
  • you can ensure the integrity of your data
  • you will empower us with finding a solution which really corresponds to your entire requirements

Typically, the option of a non-disclosure agreement will be mentioned as soon as you contact us. It is at this stage that you will simultaneously receive a questionnaire for your technical requirements.

Semi-finished products

In the following, the alloys are transformed to semi-finished products. Semi-finished products are forms of raw material that exist in a basic geometric shape. These semi-finished products are usually produced for you by first manufacturing (melting) the material and then processing / reshaping (e.g. forging, wire drawing, rolling), while heat treatment may be carried out after each step. Additionally, we produce SMA sputter targets for you: You would typically not use these as a product itself but for producing thin-film SMA applications (passive semi-finished product, see also section thermal coatings).

The semi-finished products are produced according to your requirements: If you are looking for a component or a finished system based on SMA, the semi-finished product merely constitutes an intermediate product during the production process. Some customers however prefer purchasing semi-finished products in order to carry out further processing steps on their own premises. This often applies to areas in which value chains have been subdivided for historical reasons, such as in medical technology (e.g. tubes which are processed into stents).

The semi-finished products available to you as standard are listed below: However, remember you can also obtain individual semi-finished shapes (such as bars, billets), as flat product (e.g. trapezoidal sheets) or long product (e.g. rings, discs). In individual cases, we may resort to manufacturing these together with a partner.
