Where to do the coercivity test? Where to get the coercivity test report? BAIJIAN material testing agency can provide coercivity testing services for CMA qualification certification agencies, high-tech enterprises, third-party material laboratories, and product-specific For problems encountered in R&D and quality control, we provide comprehensive solutions for component testing, product testing, product testing, instrument testing, etc. The equipment is complete and the scientific research team is strong. The test report can be issued in 7-15 working days. Scan the QR code to check the authenticity. Fake, nationwide door-to-door sampling and sample testing services, short test cycle, low test cost, scientific and accurate test data!

Test cycle: 7-15 working days

Testing fee: Engineers develop experimental plans and quote based on customer testing needs and experimental complexity .

Test item: Coercivity test

Coercivity test range

Soft magnetic materials, magnet blocks, electromagnetic pure iron, stainless steel, amorphous strips, permalloy, electromagnets, soft magnetic films, ferromagnetic materials, ultra-fine alloys, soft magnetic materials, iron-gallium alloys, pure iron, relays Parts, magnetic steel, stainless steel, permanent magnets, etc.

What are the functions of the BAIJIAN test report? What problems can it help you solve?

1. Sales use. (Sell your own products and issue third-party test reports to make customers more confident in the quality of your products)

2. Research and development use. (During the research and development process, some difficult problems are encountered, and the problems are solved through test report data, thereby shortening the research and development cycle and reducing research and development costs)

3. Improve product quality. (By comparing test data, we can discover the problems of our own products, improve product quality, and reduce production costs)

4. Use of scientific research paper data.

5. Bidding, bidding use (BAIJIAN has a relatively short test cycle, low testing costs, and high recognition, and is especially suitable for bidding)

Coercivity test related information

Coercivity means that after a magnetic material is saturated and magnetized, its magnetic induction intensity B does not return to zero when the external magnetic field returns to zero. Only by adding a certain magnetic field in the opposite direction of the original magnetizing field can the magnetic induction intensity return to zero. This magnetic field is called the coercive magnetic field, also known as the coercive force. Coercive force comes from the irreversible magnetization process. The main factors causing the irreversible magnetization mechanism are the existence of magnetic anisotropy (including magnetocrystalline, induced and stress anisotropy) as well as impurities, pores, defects, etc. in the material.

BAIJIAN sample sending test process

1. Send samples

2. Preliminary Inspect samples

3. Quotation

4. Both parties confirm, sign a confidentiality agreement, and start the experiment

5. Complete the experiment in 7-15 working days

6. Issue test report and provide post-service.

The above is the relevant introduction to coercive force testing. If you have other testing needs, you can consult the laboratory engineer to help you answer them.
