Honed tubes/pipes are also known as  hydraulic or pneumatic cylinder tubing due to their primary uses for their production or repair. They are tubes with their inside diameter either honed or skived & roller burnished resulting in extremely precise inside diameter (ID) dimensions and smooth ID surfaces. Honing is an abrasive machining process involving the use of abrasive polishing stones and abrasive paper to remove small amounts of material and improve surface geometry and surface texture.The manufacturing process is determined upon the tube dimension, mold availability and customer ewquirements. Honed tubing is used in applications where a high precise inside diameter dimension and a smooth inside surface are required.

As honed tubes are the most important materials for manufacturing and repairing hydraulic and pneumatic cylinders, the quality of the honed tube is of critical importance. Honed  tubes/pipes are offered as part of our own branded (AVIATIONEU NEW ERA) product lines in different materials, such as steel, stainless steel and aluminum alloys in various grades and tempers depending on the intended application. Sourced from quality producers, the AVIATIONEU NEW ERA honed tubing is available in different size ranges in imperial  (in.) and metric systems and pre-determined or cut to order lengths. Depending on the producer, they comply with different standards/specifications. Manufacturing test reports can be supplied upon request additional cost, unless otherwise mentioned.

Steel alloy 4130 (ST4130), also known as Chrome Moly after the 2 key elements of its composition, chromium, and molybdenum, is a general-purpose alloy steel widely used by the aviation and motorsports industries due to its weldability, fabrication, and mild hardenability in all offered forms (tubes, bars, sheets and plates). They are available in two different material states (Normalized and Annealed) depending on the process of how the material is heated and cooled.

The Normalized condition (sometimes referred to as "Condition N") is the harder and stronger condition and is best used when forming is not needed. Normalizing relieves internal stress on steel and improves toughness in steels that may harden after the cold working process. The Annealed condition (sometimes referred to as "Condition A") is the softer and formable condition and is best used when forming is needed. Annealing relieves internal stresses, softens and makes the material more ductile.

4130 alloy steel (Chrome Moly) seamless round tubes are offered in Normalized (N )  or Annealed (A) conditions as part of our own branded (AVIATIONEU NEW ERA) product lines. They have been for years the standard of the aircraft industry.

2000 series aluminum alloys, with copper as the primary alloying element, are a set of "hard alloys". They typically contain between 2 to 10% copper, with smaller additions of other elements. The copper provides substantial increases in strength and facilitates precipitation hardening but can also reduce ductility and corrosion resistance. These alloys are known for high performance and excellent strength over a broad range of temperatures   but can be the most challenging to weld. They find use in many industries, including the aerospace sector. They are essential materials in various industries such as aerospace, marine, construction, and automobile.

Aluminum alloys 6061 and 6063 (AL6061/AL6063), with magnesium and silicon as their major alloying elements, are both popular alloys used in extrusions for a variety of architectural, machinery, equipment, and consumer products. Similar in composition & mechanical properties they come as O (annealed), or in tempered grades. Their magnesium content provides increased strength, and silicon reduces their melting temperature. Their formability, weldability, corrosion resistance, and moderately high strength enhance their versatility. However, there are differences between them and factors affecting their suitability for different applications. 6061 aluminum is the most commonly used aluminum alloy in the world used in all kinds of applications ranging from electronics to welded assemblies. Compared to AL2024 (aka aircraft aluminum) 2024 aluminum’s higher yield strength makes it more suitable if strength is a priority. 6061 tubes, sheets, bars, and plates offer high- to moderate strength, excellent corrosion resistance, and superior machinability and weldability while 6063 aluminum tubes offer an excellent strength-to-weight ratio, superior corrosion resistance, and a fine appearance and finish.

Steel alloy 4130 (ST4130), also known as Chrome Moly after the 2 key elements of its composition, chromium, and molybdenum, is a general-purpose alloy steel widely used by the aviation and motorsports industries due to its tensile strength of 90,000 psi, weldability, fabrication, and mild hardenability in all offered forms (tubes, bars, sheets and plates). They are available in two different material states (Normalized and Annealed) depending on the process of how the material is heated and cooled.

The Normalized condition (sometimes referred to as "Condition N") is the harder and stronger condition and is best used when forming is not needed. Normalizing relieves internal stress on steel and improves toughness in steels that may harden after the cold working process. The Annealed condition (sometimes referred to as "Condition A") is the softer and formable condition and is best used when forming is needed. Annealing relieves internal stresses, softens and makes the material more ductile.

4130 alloy steel (Chromoly) tubes exhibit an excellent strength to weight ratio, they are malleable, very easy to weld, resistant to scaling and oxidation and have a clean, smooth finish on both the inside and the outside of the tubing. Square tubes are offered in Normalized (N) condition as part of our own branded (AVIATIONEU NEW ERA) product lines and conform to SAE AMS-T 6736 & AMS 6360 M(*) specifications.

AL2024, the so-called aircraft aluminum, is an aluminium alloy, with copper as the primary alloying element. It is used in applications requiring high strength to weight ratio, as well as good fatigue resistance, weldablility and average machinability. The addition of copper to this alloy makes 2024 one of the strongest aluminum alloys. It comes in different tempers (O without heat treatment or T with heat treatment). It is non-magnetic and heat treatable but it also is more succeptible to corrosion than most other aluminum alloys. 

Due to the poor corrosion resistance of this alloy  it is often clad (specified as CLAD or ALCLAD) in which case high-purity aluminium surface layers are metallurgically bonded to the aluminium alloy core material. 2024-T3 is typically used in structures where a high strength to weight ratio is necessary, clock parts, computer parts, hydraulic parts, bolts, valves, nuts, pistons, and gears. 

AL2024 tubes/pipes are offered as part of our own branded (AVIATIONEU NEW ERA) product lines.Tubes are designed to act as structural support, whereas pipes are designed to carry liquids and gases.
