  5. 4. Study and analysis of surface layer characteristics of lead brass and lead free brass

    Magister-uppsats, Högskolan i Halmstad/Maskinteknisk produktframtagning (MTEK)

    Författare :Dharmendra Challapalli; Ahmad El-masri; [2016]
    Nyckelord :Lead free Brass; surface integrity; subsurface deformation; microhardness.;

    Sammanfattning : The addition of lead to the copper alloys increase the machinability of thework material (without reference here to environmental factors) and reduces the overall production cost of the components at different stages, despite copper being expensive, which makes a challenging task to replace lead. Since lead is dangerous to human health. LÄS MER

  7. 5. LEAD FREE BRASS : Study and Analysis of the surface integrity of lead brass and unleaded brass.

    Magister-uppsats, Högskolan i Halmstad/Maskinteknisk produktframtagning (MTEK)

    Författare :Amogh Vedantha Krishna; Vijeth Venkataram Reddy; [2015]
    Nyckelord :Brass; Surface Integrity; Surface measurements; Surface roughness parameters.;

    Sammanfattning : The addition of lead to the copper alloys increases its machinability and reducesthe overall production cost, despite copper being expensive, which makes achallenging task to replace lead. But the alarming effects of lead on human healthand the recycling problems has led to the increase in concern forreducing/eliminating the use of lead in brass and other copper alloys. LÄS MER
