Abstract

Komposit CuSn merupakan komposit matriks logam yang dapat digunakan sebagai material bahan pembuatan peluru frangible. Pembuatan komposit CuSn dilakukan dengan menggunakan mesin kompaksi hidrolik rangka tipe 4 kolom karena memiliki efisiensi yang lebih tinggi dan instalasi yang lebih fleksibel. Besarnya tekanan yang diberikan dan waktu tahan penekanan saat proses kompaksi (dwelling time) sangatlah berpengaruh terhadap kinerja mesin kompaksi yang berdampak pada sifat mekanik produk komposit yang dihasilkan. Maka, diperlukan pengujian kinerja dan efisiensi mesin kompaksi hidrolik otomatis rangka tipe 4 kolom dan pengujian terhadap produk yang dihasilkan dengan berbagai variable tekanan kompaksi yaitu 500, 600 dan 700 Mpa dan dwelling time yaitu, 0;5;15;30;45 menit. Hasil pengujian menunjukkan sampel dengan tekanan 700 Mpa dengan dwelling time 15 menit memiliki nilai optimum untuk densitas, kekerasan dan juga kekuatan tekan dengan nilai sebesar 8,454 gr/cm3, 87 HRF dan 349,74 Mpa. Hasil uji SEM/EDX menunjukkan bahwa pada tekanan 700 Mpa densifikasi serbuk terjadi paling baik. Mesin kompaksi hidrolik 4 kolom memiliki akurasi penekanan sebesar 100%, dengan efisiensi mesin sebesar 80%, serta efisiensi produksi sebesar 73%.

CuSn composite is a metal matrix composite that can be used as a material for making frangible bullets. The manufacture of CuSn composites is carried out using a 4-column frame hydraulic compacting machine because it has higher efficiency and more flexible installation. The amount of pressure applied and the holding time of the compression during the compacting process (dwelling time) greatly affect the performance of the compacting machine which has an impact on the mechanical properties of the resulting composite product. Therefore, it is necessary to test the the 4-column frame type automatic hydraulic compacting machine and test the resulting product with various compaction pressure variables, namely 500, 600 and 700 Mpa and dwelling time, namely, 0; 5; 15; 30; 45 minutes. The test results show that the sample with a pressure of 700 Mpa with a dwelling time of 15 minutes has the optimum values for density, hardness and compressive strength with values of 8.454 gr/cm3, 87 HRF and 349.74 Mpa. The results of the SEM/EDX test showed that at a pressure of 700 Mpa the best powder disinfection occurred. The 4-column hydraulic compaction machine has a pressing accuracy of 100%, with a machine efficiency of 80%, and a production efficiency of 73%.
