Classification of Engineering Materials Part 2

Non - Ferrous Metals


  • Aluminum and its alloys
  • Copper and its alloys
  • Magnesium and its alloys
  • Nickel and its alloys
  • Titanium and its alloys
  • Refractory metals

Aluminum and its alloys


1.High strength to weight ratio
2.Resistance to corrosion
3.High thermal and electrical conductivity
4.Ease of machinability
5.Non-magnetic

Magnesium and its alloys


•Magnesium (Mg) is the lightest metal. 

•Alloys are used in structural and non-structural applications. 

•Typical uses of magnesium alloys are aircraft and missile components. 

•Also has good vibration-damping characteristics.

Copper and its alloys

•Copper alloys have electrical and mechanical properties, corrosion resistance, thermal conductivity and wear resistance. 
•Applications are electronic components, springs and heat exchangers.
•Brass is an alloy of copper and zinc.
•Bronze is an alloy of copper and tin.


Nickel and its alloys

•Nickel (Ni) has strength, toughness, and corrosion resistance to metals.
•Used in stainless steels and nickel-base alloys.
•Alloys are used for high temperature applications, such as jet-engine components and rockets.

Titanium and its alloys


  • Titanium (Ti) is expensive, has high strength-to-weight ratio and corrosion resistance.
  • Used as components for aircrafts, jet-engines, racing-cars and marine crafts.

Refractory Metals


•Refractory metals have a high melting point and retain their strength at elevated temperatures. 

•Applications are electronics, nuclear power and chemical industries. 
• Molybdenum, columbium, tungsten, and tantalum are referred to as refractory metal. 

Other Non-Ferrous Metals

Low melting point metals
  • Lead
  • Zinc
  • Tin
Precious Metals

Components of Computer Network

Image
Components of Computer Network  The  components that make up a computer network are -  1. Client  2. Server  3. Middleware  4. Router and Switch  5. IP address  Client - Client is a computer that retrieves information from or uses resources provided by the server or main computer. Server - A server is an instance of a computer program that accepts and responds to requests made by client.  Servers are used to manage network resources.  For example, a user may setup a server to control access to a network, send/receive e-mail, manage print jobs, or host a website.  Application Servers  Audio/Video Servers Chat Servers  Fax Servers  FTP Servers  Groupware Servers  IRC Servers  List Servers  Mail Servers Proxy Servers  Telnet Servers  Web Servers Middleware is the software that connects two otherwise separate applications. Most network...

Negotiable Instrument - Cheque

Image
Characteristic Features of a Cheque -  A cheque is always drawn on a banker or in other words, the drawee of a cheque is always a bank. It is always payable on demand and does not require acceptance. Cheques may be payable to the drawer himself. It may be made payable to the bearer on demand unlike a bill or a note. The banker is liable only to the drawer. A holder has no remedy against the banker if a cheque is dishonoured. Cheques are exempted from payment of stamp duty, unlike certain classes of bills. A grace period of 3 days is allowed for a Bill. There is no such provision for a cheque. A cheque can be drawn where the drawer has a bank account. A cheque is valid only for three months from the date of the cheque. Dishonour of Cheque   A cheque is said to be dishonoured, when it is not paid when demanded for certain reasons.  Some of the reasons why a bank dishonours a cheque Where the drawer countermands payment or stops payment of the cheq...

Avionics - Typical Electronic / Digital Aircraft System

Image
General electronics/digital aircraft systems are -  ECAM (Electronic Centralized Aircraft Monitoring) EFIS (Electronic Flight Instrument System) EICAS (Engine Indicating & Crew Alerting System) FMS (Flight Management System)      ECAM (Electronic Centralized Aircraft Monitoring) An  electronic  centralized  aircraft monitor  (ECAM) is a system, developed by Airbus , that monitors aircraft functions and relays them to the pilots.  ECAM produces messages detailing failures and in certain cases, lists procedures to undertake to correct the problem. Airbus developed ECAM, such that it not only provided the features of (Engine Indicating and Crew Alerting System)EICAS, but also displayed corrective action to be taken by the pilot, as well as system limitations after the failures. Using a color-coded scheme the pilots can instantly assess the situation and decide on the actions to be taken. ECAM was  designed to...
