Safety information:
Metal dust is harmful to health. Use dust extraction when finishing and blasting. The fumes, smoke and dusts formed during processing (e.g. grinding, polishing, melting): May cause an allergic skin reaction (H317). May cause allergy or asthma symptoms or breathing difficulties if inhaled (H334). Wear respiratory protection in case of inadequate ventilation. The alloy in solid form (as supplied) does not require labelling. Hypersensitivity to components of the alloy must be taken into account. If intolerance to individual elements of this alloy is suspected, it should not be used. Observe the instructions for use and the safety data sheet (see downloads).
