Unfortunately lead affects the haematological and nervous system. Therefore copper alloys containing lead represent one of the greatest problems in world production. Research Material Institute in Panenske Brezany together with the Department of Machining, Process Planning and Metrology CTU in Prague developed new environmentally friendly cooper alloys. Some of the research results related to surface roughness are presented."@en . "Surface Roughness in Machining Free-Machining Environmentally Friendly Cooper Alloys"@en . .
