Introduction Metallic yarns or threads‚ in general‚ have been known for more than 3000 years. Gold and silver were hammered into extremely thin sheets‚ then cut into ribbons and worked into fabrics. These were the first ‘man made’ fibres‚ which came thousands of years before nylon or rayon. The Persians made fabulous carpets with gold thread and the Indians‚ ornamental sarees with it. The metal threads were twisted‚ doubled or wrapped around some other thread such as cotton. With the advancement

This project is called “Bandar Hijau Serdeng”‚ collaboration between UPM with the Subang Jaya Municipal Council (MPSJ0 which involved in activities from simple “3R’’ proses which includes reduce‚ recycle and reused campaigns. Extension to this project‚ UPM has decided to build a pavilion for the purpose of providing a place to sit and enjoy the scenery of Serdang town

EXTRACTION OF COPPER FROM OXIDISED COPPER ORE Aim: To analyse how copper is obtained from oxidised copper ore using the processes of leaching‚ solid-liquid separation‚ displacing and electrowinning. Method: Refer to ‘Extraction of Copper from oxidised Copper Ore’ document pages 1-2 Results: Leaching: The blue particles in the copper ore which is copper was dissolved in the sulphuric acid and the solution turned into a blue colour. There was also sediment that was floating around

Introduction: Generally‚ there are oxides of metals and non-metals. Metals burn in oxygen to form basic oxides while non-metals form acidic oxides. Structurally‚ they are covalent or ionic compounds. You are to

During the experiment‚ aluminium and mild steel was used to demonstrate how the materials behave during the testing condition. By measuring the applied torque with respect to the angle of twist‚ the Torsional rigidity (GJ)‚ the Modulus of Rigidity (G) and the shear yield stress (τ) for ductile materials‚ mild steel and aluminium. INTRODUCTION The purpose of this experiment is to study and to compare the behaviour of ductile

Al-B4C composites. Attempts were made to overcome the wetting problem between B4C and liquid aluminium at lower temperatures for promising the mechanical and tribological behaviour of the Al -B4C composites. AA6061-B4C particle reinforced composites were produced through casting route at 850ºC with K2TiF6 added as flux to overcome the wetting problem between B4C and liquid aluminium metal. The Aluminium B4C composite samples were subsequently subjected to T6 heat treatment. The composite samples

The Vickers number of hardness for cold rolled specimens can be show very clearly that it has increasing up the number itself likewise the number of thickness reduction which also increasing. Which its number of Vickers can be rated as follow as Aluminium < Copper < Brass ; this means that Brass has the most tensile strength‚ Aluminium is easily to bend and
