EGA Master offers the widest range of non-spark tools, manufactured in two main types of alloys: aluminium bronze (Al-Bron) and copper beryllium (Cu-Be).

EGA Master's anti-spark tools are certified by the BAM Institute, approved by the European Union to be certified based on directive 94/9/EC.

Egamaster - Non-Sparking Tools

EGA Master non-sparking tools are the best alternative for non-sparking application purposes in potentially explosive enviroments. All tools are forged after casting to achieve the best quality in the market, both in mechanical properties and attractive finishing. We incorporate to our non-sparking tools all our knowledge of decades designing and manufacturing hand tools, making the most ergonomic, easy-to-be-used and nicest design for them.

All EGA Master tools are manufactured according to the strict control of ISO 9001-200, certified by the most prestigious institution for hand tool manufacturing, TÜV-Rheindland/Germany.

    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: 283-365 Brinell for those made in copper-beryllium and 229-291 Brinell for those made in aluminum bronze.

    • Features and Alloy Properties of EGA Master's anti-spark tools.

    Property Aplication or benefits
    Non-sparkingAppropriate for explosive potential environments.
    Non-magnetic safetyEssential for equipments that require complete non-magnetic safety.
    Corrosion resistant Specially well suited for applications in corrosive environments like encountered in marine works or fire-fighting applications.
    Forged after casting rovides higher mechanical properties and better finishing.
    Ergonomic designsThe use of bi-material anti-slippery handles, dipping anti-slippery handles, totally ergonomic designs make operations easier, more comfortable and master.


    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, specially in the presence of moisture.

    • Among the advantages and differences between the copper-beryllium alloy and the aluminium-bronze alloy we highlight the following.

    Concept Cu-Be Al-Bron
    Hardness283-365 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 make it appropiate for non critical non-magnetic applications.
    DurabilityMuch higher due to the higher hardness and tensile strength. Higher efforts can be made. Not as much as Cu-Be.
    PriceHigher price due to the special raw material used. Around 30 % lower price.

    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-Bron 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).

  • Items with copper compositions higher than 65 % should not be used in acetylene enviroments. Both aluminium-bronze and copper-berylium allows do have higher copper compositions than 65 %. Reason is not that copper-berylium can create a spark with the 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 enviroments. EGA Master, S.A is working in a newly developed non-sparking alloy that may be 100 % safe to be employed in acetylene enviroments. If that is your situation, please contact us to be informed about the availability.

      • 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.
      • To avoid damage being caused to both tool and fastener, it is necessary to always ensure that the correctly sized spanner/wrench/screwdriver is selected. Due to the reduced strength and wear resistance of non-sparking Alloys selecting the correctly sized tool becomes essential to avoid premature wear and early deterioration of the tool.
      • 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.
