Non–Sparking Tools

Thomas Warburton now stock EGA Master Non-Sparking Tools which are the best alternative for non-sparking application purposes in potentially explosive environments. All tools are forged after casting to achieve the best quality in the market, both in mechanical properties and attractive finishing. We incorporate in our non-sparking tools all our knowledge gained over decades, designing and manufacturing hand tools, making the most ergonomic and nicest design for them.

Important Note

The hardness and resistance that can be achieved with the materials used to manufacture non-sparking tools is significantly lower than that which can be obtained in tools made of steel. Due to these special characteristics of the material employed, non-sparking tools can not be guaranteed against any deformation or breakage. Non-sparking tools will be replaced under guarantee only when the hardness of the damaged tool does not reach (or exceeds) the one indicated in our catalogue: 35-40 HrC for those made in Copper-Beryllium and 25-30 HrC for those made in Aluminium Bronze.


Properties And Features

Property

Application or Benefits

Non-sparking

Appropriate for explosive potential environments

Non-magnetic safety

Essential for equipment that requires complete non-magnetic safety

Corrosion Resistant

Specially well suited for applications which encounter corrosive environments including marine works or fire-fighting applications

Forged after casting

Provides higher mechanical properties and better finishing

Ergonomic designs

The use of bi-material anti-slip handles, dipped anti-slip handles and ergonomic design makes mastering operating much easier and more comfortable


Differences and How to Make the Correct Choice

Concept

Cu-Be

Al-Bron

Hardness

283-365 Brinell

229-291 Brinell

Magnetism

Non ferrous substance in the composition makes it safer when non-magnetic applications are required

Minimum ferrous component makes them not 100% non-magnetic, although its low magnetism makes it appropriate for non-critical non-magnetic applications

Durability

Much higher due to the higher hardness and tensile strength. Higher efforts can be made.

Not as much as Cu-Be.

Price

Higher price due to the special
raw material used.

Around 30% lower in price

Caution

These tools are not classified as anti-static because they do conduct electricity. Do not use high copper content tools (>65%) in direct contact with acetylene due to the possible formation of explosive acetylide, especially in the presence of moisture.

Tools made of Cu-Be alloy can be used in all groups (I, IIA, IIB, IIC) in a safe way, always respecting the maximum surface temperature allowed, with the only exception of acetylene, with which copper might react and create highly explosive acetylite gases.

Tools made of Al-Bronze alloy can be used in a safe way, always respecting the maximum surface temperature allowed, except for the IIC group (Hydrogen, gas of water, acetylene, bisulphide of carbon, Ethyl nitrate).

Copper or Brass Tools

Copper or brass tools are safe in explosive environments of risk groups I and IIA. It is safe to work with them in these environments. EGA Master has available a complete range of copper and brass hammers and mallets made in both materials. It is convenient to know that copper or brass tools can never be considered as alternatives to aluminum-bronze or copper-beryllium alloy tools, because their hardness is too low for most applications. There is the temptation to choose copper or brass tools due to their lower cost compared to aluminum-bronze or copper-beryllium ones. This choice is not only risky in itself, but in the short/mid term it will be necessary to replace them for new ones for the wearing out suffered due to their low hardness.

For this reason, copper or brass tools should only be used in those jobs that have to be made in risky environments (I and IIA), if the same job would be made with copper or brass tools in a non-risky environment. In case you would use a steel tool in a non-risky environment, than you should choose for your safety and profitability tools made in aluminum-bronze or copper-beryllium alloys to make the same job in a risky environment, never a copper or brass tool.

Acetilex Alloy, Safe Work Even in Acethylene Environments

Items with copper compositions higher than 65% should not be used in acetylene environments. Both aluminium bronze and copper-beryllium alloys do have higher copper compositions than 65%. The reason is not that copper beryllium can create a spark with enough energy to create the ignition of acetylene, but that copper can react with acetylene creating highly explosive acetylates.

For this reason, copper-beryllium or aluminium-bronze alloys should not be used in acetylene environments. Ega Master S.A., is always committed to finding new innovative solutions that will increase safety, we have developed the ACETILEX alloy, 100% safe to be used in acethylene environments. Once again, pioneers in safety.

Instructions For Use & Warranty

  1. Non-Sparking Tools cannot reach the hardness of conventional tools. For this reason the use of Non-Sparking Tools has to be carried out with special care, avoiding overstraining, heating, etc.
  2. The use of Non-Sparking Tools must not be the only preventive measure in areas which the items are designed for. Other items, clothes or present material must also be adequate for non-sparking purposes.
