Non Sparking Tools

EGAMASTER, S.A. are the preferred supplier for Non-Sparking Copper-Beryllium or Aluminum-Bronze Tools. We have combined unsurpassed quality with decades worth of design and manufacturing knowledge to create a comprehensive range of hand-tools designed for potentially explosive environments. Our tools are forged after casting which allows us to achieve unparalleled excellence, all while ensuring ease of use along with an ergonomic design.

EGAMASTER, S.A. Non-Sparking Range caters for the use of tools within the I, IIA, IIB, IIC groups. Contact us for any further explanation of these groups, or to determine which alloy would suit your application best.

Due to the alloys used during the manufacturing of our Non-Sparking Tool range, the hardness and resistance expected from steel tools cannot be equaled.
All EGAMASTER, S.A. tools are manufactured according to, and maintain the strict control of ISO 9001-200, certified by the most prestigious institution for hand tool manufacturing, TÜV-Rheindland/Germany. EGA Master non-sparking tools are also BAM certified by the prestigious German Federal Institute for Materials Research and Testing, which is a European Union approved laboratory to certify according to 94/9/EG Directive (Atex).

Property Aplication or Benefits
Non-sparking Appropiate for explosive potential enviroments .
Non-magnetic safety Essential for equipments that require complete non-magnetic safety
Corrosion resistant Specially well suited for applications in corrosive enviroments like encountered in marine works or fire-fighting applications.
Forged after casting Provides higher mechanical properties and better finishing.
Ergonomic designs The use of bi-material anti-slippery handles, dipping anti-slippery, totally ergononomic desings make operations easier, more confortable and master.

CAUTION: These tools are not clasified as anti-static because they do conduct electricity. Do not use high copper content tools in direct contact with acetylene due to the possible formation of explosive acetylide, specially in presence of moisture.


Concept Cu-Be Al- Br
Hardness 35-40HRc 25-30HRc
Magnetism Non ferrous substance in the composition makes it safer when non-magnetic applications are required. Minimun ferrous components makes them not 100% non-magnetic, although its low magnetism make it appropiate for non critical non-magnetic applications.
Durability Much higher due to the higher hardness and tensile strength. hogher efforts can be made. Not as much as Cu-Be.
Price Higher 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 maximun surface temperature allowed, except with acetylene that can create explosive acetylite gases.

Tools made of Al-Bronze alloy can be used in a safe way, allways respecting the maximun 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. EGMASTER, 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 hardnes 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.
