At Cangzhou Dean Safety&Special Tools Co., Ltd (Est. 2001, annual export value above US$100 million), we offer the Anti-magnetic Double Open-Ended Wrench – a premium solution for environments where sparks and magnetic interference are unacceptable. This wrench is engineered from specialized non-ferrous alloys (beryllium copper or aluminum bronze), ensuring zero magnetism while delivering exceptional strength and corrosion resistance. Each tool comes with a 1-year warranty and a Mill Test Report (MTR) upon request, guaranteeing full traceability of material composition and mechanical properties.
Our wrench complies with internationally recognized standards (ASTM, DIN, GB/T), making it a trusted choice for demanding sectors such as oil & gas, chemical processing, mining, aerospace, and marine maintenance. The double open-end design provides two different jaw sizes per tool, increasing versatility and reducing the need to carry multiple wrenches. Whether you work in explosive atmospheres or near sensitive electronic equipment, this anti-magnetic wrench delivers reliable performance without risk of spark generation or magnetic attraction.
Key Features & Benefits
- Anti-magnetic property: Made from beryllium copper or aluminum bronze, these materials have negligible magnetic permeability, ideal for use in MRI rooms, ordnance handling, and electronics assembly.
- Non-sparking safety: The non-ferrous composition eliminates the risk of sparks upon impact, critical in flammable gas, vapor, or dust environments.
- Double open-end design: Each wrench features two different-sized openings (e.g., 10×12mm, 13×15mm), allowing you to work on two fastener sizes with one tool.
- Corrosion resistance: Resists rust and chemical attack, suitable for offshore, marine, and chemical plant applications.
- High torque capacity: Precision forging and heat treatment ensure the wrench can handle substantial tightening and loosening forces without deformation.
- Standard compliance: Manufactured per ASTM B124, DIN 3113, and GB/T 4394, with full dimensional and hardness testing.
- Mill Test Report included: Every batch can be supplied with an MTR detailing material chemistry and mechanical properties, satisfying quality audits.
- 1-year warranty: Covers manufacturing defects, giving you peace of mind.

Frequently Asked Questions (FAQ)
-
Q1: What does "anti-magnetic" mean for a wrench?
A: An anti-magnetic wrench is made from materials with very low magnetic permeability (μ -
Q2: Is this wrench suitable for use in explosive atmospheres?
A: Yes. The non-sparking property of beryllium copper or aluminum bronze significantly reduces the risk of ignition in flammable gas, vapor, or dust zones. However, always follow your site’s safety guidelines. -
Q3: Can I get a Mill Test Report for each batch?
A: Absolutely. We provide a Mill Test Report (MTR) upon request and as standard for many orders. The report includes material chemistry, hardness, and tensile test results. -
Q4: What standards does this wrench comply with?
A: Our products are manufactured to meet ASTM B124, DIN 3113, and GB/T 4394 requirements. We can also adjust to other industry standards upon request. -
Q5: What sizes are available? Can I order custom sizes?
A: We offer a wide range from 6×7 mm up to 46×50 mm. Custom sizes and combinations are available – just provide your specifications. -
Q6: What is the difference between beryllium copper and aluminum bronze?
A: Beryllium copper offers higher strength and hardness (up to 38 HRC) and slightly better anti-sparking performance. Aluminum bronze provides excellent corrosion resistance at a lower cost. Both are non-magnetic. -
Q7: How long is the warranty, and what does it cover?
A: We offer a 1-year warranty covering defects in material and workmanship under normal use. Excludes misuse or intentional damage. -
Q8: Do you offer sample testing before bulk order?
A: Yes, we can provide samples for evaluation. Sample cost is negotiable, and we can arrange for dimensional and magnetic permeability testing upon request.
