Stone<\/h2>\n

<\/p>\n <\/div>\n [vc_column_text]In the mining industry<\/strong>, cemented carbide is the core component.<\/h1>\n

Stone cutting tools are used on all machinery for digging rocks <\/strong>work thanks to tungsten carbide. Tunnels are perforated by cutting tool drills made of tungsten carbide, for example the excavation of the Channel Tunnel<\/a> between France and England.<\/p>\n

This large projects as tunnel drilling or mining to be successfully and economically, reliable carbide tools are decisive: they have long tool life, they provide high hardness and corrosion resistance, high toughness as well as compressive strength.<\/p>\n

The experience gained over the years in mining and stone processing enabled us to develop specific carbide grades<\/a> for stone cutting tools that allow us to easily undertake different types of processing: (rotation, percussion, roto-percussion, <\/strong>abrasion<\/strong>, etc.) on different types of rock and soil: (sandstone, concrete, tuff, quartzite, porphyry, lava stone, marble<\/strong>, etc.).<\/p>\n

For all applications we offer a wide range of shapes on customer drawings for their machines, as well as a large selection of tungsten carbide grades customised for stone and geological conditions. Grade variants in grain size and composition as well as in special additives.<\/p>\n

We produce every type of widia plate both for brazing and for mechanical fixing, such as:<\/p>\n
