Aluminum Aircraft Alloy for Aviation
Humans have gained frontline skills in metallurgy as the associated procedures enable us to extract metals and their alloys and shape them into suitable shapes to satisfy various aspects of existence and progress.
Our developmental approach heavily relies on metals, which explains the synergy with metallurgy! Metal items are manufactured in various ways based on the type and needs of applications.
Bars and rods are common items, and their applications span from building structures and axles to diverse frameworks.
Metals may be made in many different sizes and forms. These forms, such as tubes or pipes, may appear identical yet have distinct properties and purposes.
It also applies to two circular shapes:
- round bar
- precision ground bar
Round Bar
The term “round bar” refers to a cylindrical long metal bar with several commercial and industrial applications. The shaft is the most widespread use. The diameter of the round bar ranges from 1/4″- 24″. It is also available in other sizes. Round steel comes in various types, including cold rolled steel, hot rolled steel, stainless steel bar stock, alloy steels, etc.
Round Bar Classification
By Process
Hot rolling, cold drawing, and forging are the three types of round bar. The hot rolled bar standard is 5.5mm to 250mm.
Round bars of 5.5mm to 25mm are frequently sold in straight bar bundles and are often used as bolts, steel bars, and different mechanical parts. The round bar greater than 25 mm is primarily used for producing mechanical parts, tube billets, etc.
By Chemical Compositio
Carbon steel is classified into three types based on its carbon content (chemical composition: low carbon steel, medium carbon steel, and high carbon steel.
Low carbon steel
It is also called mild steel. It has 0.10-0.30% carbon content and can be quickly processed, such as cutting, welding, and forging. It’s commonly used to make rivets, chains, bolts, and shafts.
Medium carbon steel
It is a type of carbon steel having a carbon content ranging from 0.25-0.60%. It also contains manganese in a small quantity of about 0.70– 1.20%. It may be split into two types based on the quality of the product: ordinary carbon steel and high-quality carbon steel. The hot working, as well as cutting capabilities, are excellent, but the welding capabilities are lacking. The hardness and strength of this steel are more than those of low carbon steel, but the toughness and plasticity are lower. Materials that have been hot rolled or cold drawn could be utilised before and after the heat treatment. After tempering and quenching, medium carbon steel possesses good overall mechanical qualities. As a result, medium carbon steel is commonly employed in applications requiring medium strength. It is widely employed in the fabrication of several mechanical parts and is also used as a construction material.
High carbon steel
It has carbon content ranging from 0.60-1.70 %, and it can be tempered and hardened. Cutting tools like drills, reamers, taps, crowbars, and hammers are made from high carbon steel.
By Material
Steel Round Bars
Steel round bars come in two types: hot rolled and cold rolled. Hot-rolled round bars are often used in construction applications where a perfect finish and accurate dimensions are not required. Cold rolled round bars are utilised for applications that need a perfect finish and precise dimensions. Steel round bar is commonly used in frameworks, braces, supports, axles, and shafts.
Stainless Steel Round Bars
Stainless steel bar stock has corrosion-resistant properties. The Stainless steel bar stock can withstand high acidity levels and may be utilised in chlorinated or alkaline conditions. Stainless steel bar stock is used in machine components, construction, automobiles, etc.
Aluminum Round Bars
Aluminium round bar stock is lightweight and corrosion-resistant. Aluminium round bar stock can be easily machined and cut. An Aluminium round bar stock is commonly used for supports, shafts, trim, braces, dowels, and pins.
Brass Round Bar
Brass round stock is usually used when electrical conductivity, strength, spark resistance, and corrosion resistance are essential. Brass round stock can also be easily machined and has lustre when polished. Brass round stock is used in Marine hardware, fasteners, fittings, and instruments.
Precision Ground Bar
Precision Ground Bar is, also referred to as ‘Turned Ground and Polished’ shafting, is a term used to describe circular bars that have been finely ground and polished from high-quality steel. They are highly polished to guarantee that the surfaces are immaculate and straight. Surface polish, roundness, straightness, and hardness are held to exceptionally close tolerances during production, ensuring high durability and minimal maintenance.
Manufacturing Process
Induction hardening is used to manufacture precision ground bars.
Induction hardening
It is a process in which heat does not come in direct contact; instead, heat is generated by electromagnetic induction. The steel gets set into a strong magnetic field that allows an electrical flow to pass from the metal, producing heat. The steel’s core is unaffected by this procedure and preserves its physical qualities. The steel is then quenched in either oil, water or any other specific polymer, causing a surface layer to harden into the martensitic structure.
Applications of Precision Ground Bar
The precision ground bar is widely used in applications that need great precision, such as
- weather measuring devices
- laboratory tools
- high-speed motor shafts
- drive shafts
- pump shafts
- ball bushings
The bar is typically needed to spin at high rates in these instances. As a result, exceptional straightness is essential for preventing undesired vibration and bearing wear.
Characteristics of Precision Ground Bar
Three main characteristics of precision ground bar distinguish it as a unique product:
● Improved roundness
● Improved straightness
● Tolerance for diameter consistency
