Hempcrete

Hempcrete is a mixture of hemp hurds (shives) and lime (possibly including natural hydraulic lime, sand, pozzolans or cement) used as a material for construction and insulation.It is marketed under names like Hempcrete, Canobiote, Canosmose, and Isochanvre.Hempcrete is easier to work with than traditional lime mixes and acts as an insulator and moisture regulator. It lacks the brittleness of concrete and consequently does not need expansion joints.

CHAPA ALUMINIUM 1mm

By Adhitya Rathinam | Published: October 17, 2014

SCIENTIFIC NAME:

Aluminium 3003-H14 (AL 3003-H14)

It was Sir Humphry Davy in the 1800s that he named it. It was from the word Alumen which means ‘to have a bitter taste.

FORMULA/CHEMICAL COMPOSITION:

Aluminium alloys in which aluminium (Al) is the predominant metal.The typical alloying elements are copper, magnesium, manganese, silicon, tin and zinc. 3000 series are alloyed with Manganese.

MATERIAL DESCRIPTION:

Aluminium Sheet is metal formed by an industrial process into thin, flat pieces. It is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Aluminium is also a popular metal used in sheet metal due to its flexibility, wide range of options, cost effectiveness, and other properties. The four most common aluminium grades available as sheet metal are 1100-H14, 3003-H14, 5052-H32, and 6061-T6.

EXTRACTION PROCESS:

In its alloy form Aluminium passes through a hot-rolling mill and is then transferred to a cold-rolling mill, which can gradually reduce the thickness of the metal down to as low as 0.05 mm. Rolled products are categorized as either foil (less than 0.2 mm thick), sheet (0.2-6 mm), or plate (thicker than 6 mm).

BASIC PROPERTIES:

Comprehensive Strength [N/M2]: 14×10^{^6} N /M2

Tensile Strength [N/M2]: 15×10^{^7} N /M2

Stiffness [N/M2]:

Density [KG/M3]: 2730 KG/M3

RECYCLABLE:

Fully recyclable with no downgrading of quality, aluminium is the most cost-effective material to recycle In fact, 75% of the aluminium produced since its discovery is still in use today.

Laser: Effective

Milling: Effective

3D Printing: Effective

ADVANTAGES IN THE CONTEXT OF DIGITAL FABRICATION:

AL 3003 H14 is relatively low in cost and widely available. The main alloying ingredient is manganese which makes it a good choice for spun, formed or stamped parts and can be easily welded. 3003 has excellent workability, weldability, and good corrosion resistance. Typical applications for 3003 H14 include: mail boxes, cabinets, fan blades, awnings, siding, kitchen equipment, decorative trim, architectural uses, signage applications, etc.
