The Department of Mechanical Engineering organized a dinner talk on “Non-ferrous Metals in Construction Industry and their Production Prospect in HK” on 18 March 2016 on PolyU campus. Over 100 senior executives and engineers of the industry and representatives of engineering-related associations attended the Talk.
In a recent lead induced incident, it brings up an issue that materials containing toxic elements would generate severe political, environmental and economic effects to the general public. It may result in affecting the human health and degrading the performance of structures. In this regard, the Department of Mechanical Engineering held a knowledge transfer session and had the honor to invite Mr Alan Chan, Technical Development Manager of Lee Kee Group to share the characteristics of different types of non-ferrous metals and their applications.
Non-ferrous metals are those metals that do not contain iron as a principle ingredient, for example, zinc, aluminum, tin, copper and many others. These types of metals are widely used in a variety of industrial applications, in which many of them can be found in the construction industry. There is no doubt that these metals can provide many advantages over iron with specific mechanical, materials and chemical properties, such as high strength-to-weight ratio, non-toxic and non-corrosive characteristics, high conductivity and etc., to suit the needs for different working and operational conditions.
Followed by the opening address delivered by Mr Patrick Chan, Director of Lee Kee Group, Mr Alan Chan introduced the use of non-ferrous metals in the construction industry along with some common pitfalls in usage and quality control. Also, the introduction of galvanizing zinc and lead free tin solder were covered.
