When selecting the right alloy for your non-sparking, non-magnetic safety tools, you have two choices: copper beryllium tools or aluminum bronze tools. It’s important to keep a few key properties in mind: zone compatibility, hardness, durability, magnetic properties, and composition.
Different zones require certain alloys. Our copper beryllium tools fulfil ATEX requirements for work in a number of zones, including 0, 1, and 2 (for gas, mists, or vapors); 20, 21, and 22 (for dusts); and M1 and M2 (mining). CS Unitec’s aluminum bronze tools are appropriate for work in zones 1 and 2, and 21 and 22. Beryllium copper tools can handle more environments.
Hardness is an aspect to keep in mind in this selection process as well. Our aluminum bronze alloy tools have a hardness of 27 HRC. If your application requires a tool with higher hardness rating, copper beryllium equipment, with an HRC of 38, is a good choice.
Beryllium copper tools are extremely durable, due to the alloy’s tensile strength and high hardness. Aluminum bronze tools, because of their chemical composition, are not as durable as copper beryllium equipment.
Magnetic properties of these alloys are another important aspect in choosing the correct tool for your application. If you need a tool for non-critical, non-magnetic applications, aluminum bronze equipment features low magnetism due to its minimal ferrous composition. Beryllium copper tools have a more non-ferrous composition, so this equipment is safer for applications that require non-magnetic properties.
Check out the composition qualities of each alloy below to see which works best for your application. Each user must follow all appropriate safety regulations when choosing a tool for their particular working environment.
Copper beryllium tools and aluminum bronze tools both offer a range of great qualities and usage. For more information, check our descriptive table below.
The tools used in explosion-hazardous places must be made of special materials that do not produce frictional sparks, impact sparks, or even hot, high-temperature surfaces. Such tools are called explosion-proof tools.
Explosion wrenches, explosion screwdrivers, and vices are often used together, causing "slip" problems. In order to prevent this problem, the blade of the screwdriver should be selected correctly, and the vise should ensure proper tightness.
Appropriate applications include oil drilling platforms, petrochemical plants, oil refineries, natural gas installations, ammunition plants, varnish factories, sugar refineries, grain silos, mining and other industries where non-sparking safety tools are required. The non-magnetic feature of these alloys also makes them ideal for working on special machinery with powerful magnets such as MRI machines, military de-mining and explosives.
Non-Sparking, Non-Magnetic Beryllium Copper Tools are drop forged for the highest quality in hand tools. These corrosion-resistant tools are suitable for use in shipyards, laboratories, and paper and pulp mills, as well as in the pharmaceutical, food product manufacturing and wine industries.
The utilization of beryllium copper imparts several distinctive characteristics to tools:
High tensile strength
Excellent thermal conductivity
Resistance to corrosion and wear
Low magnetic permeability
Exceptional Strength and Durability
Beryllium copper tools excel in strength-demanding tasks, ensuring longevity and reduced need for frequent replacements.
High Thermal Conductivity
The high thermal conductivity of beryllium copper prevents overheating, enhancing operational efficiency in various applications.
Beryllium copper's resistance to corrosion extends the lifespan of tools, even in challenging and corrosive environments.
Non-sparking tools protect against both fire and explosion in environments that may contain flammable liquids, vapors, dusts or residues. ... Beryllium alloys are less favorable due to the potential toxicity of beryllium dust. Non-metals such as wood, leather and plastics can also be used to create non-sparking tools.
Beryllium copper screwdrivers, pliers, wrenches, cold chisels, knives, and hammers are available for environments with explosive hazards, such as oil rigs, coal mines, and grain elevators. An alternative metal sometimes used for non-sparking tools is aluminium bronze.
Common non-sparking tools are made of:
For example, beryllium has been associated with several health issues including cancer. While exposure to beryllium dust is likely very low with the general use of non-sparking tools, it may be a consideration grinding or polishing the tool itself.
Beryllium copper tools can be slightly more expensive due to the alloy's unique properties, but their longevity often justifies the investment.
Proper handling and adherence to safety guidelines minimize the risk of beryllium exposure.
While versatile, beryllium copper tools are best suited for specific applications where their properties shine.
Recycling beryllium copper is recommended to reduce environmental impact.
