CZ121 Brass

This material is brilliant for milling, turning and drilling purposes. Perfect for the model engineer and machinist.

CZ121 is the standard European grade of free-machining brass consisting of a duplex structure and a 3% lead addition. The particles of lead are finely dispersed throughout the microstructure and acts as both a lubricant and a chip breaker to give the alloy its free machining characteristics.

The machinability rating of 100% for CZ121 is the standard against which all other copper alloys are rated. It is the most widely used of all the brasses due to its suitability for high speed machining operations and also the manufacture of intricate parts. Its combination of machinability, thread rolling and knurling characteristics, combined with its good strength, an ease of soldering / brazing and a high resistance to corrosion makes it the ideal choice for many brass components throughout industry.

Typical Uses:

Traditional uses for CZ121 include a wide variety of machined components made on high speed lathes including screws, bolts, nuts, bushing, pins, washers, butts, hinges and also locks and components for watches.

Machinability:

This grade is particularly well suited to machining.

Stainless Steel T303

Alloy 303 is a non-magnetic, austenitic stainless steel that is not hardenable by heat treatment. It is the free machining modification of the basic 18% chromium / 8% nickel stainless steel. Alloy 303 was specially designed to exhibit improved machinability while maintaining good mechanical and corrosion resistant properties Due to the presence of sulfur in the steel composition, Alloy 303 is the most readily machineable austenitic stainless steel; however, the sulfur addition does lower Alloy 303’s corrosion resistance to below that of Alloy 304. Like other austenitic grades, Alloy 303 demonstrates excellent toughness, although the sulfur does reduce this a little as well.

Applications:

Alloy 303 is frequently used in applications that require parts to be heavily machined. Some examples include:

    Nuts and bolts

    Aircraft fittings

    Gears

    Screws

    Shafts

    Electrical switchgear components

    Bushings

Aluminium

This material is brilliant for milling, turning and drilling purposes. Perfect for the model engineer and machinist.

Application:

Commonly used where mechanical strength is of importance, such as bridges, trusses and the transport industry. Very good corrosion resistance. Suitable for general use.

This grade is particularly well suited to machining.

  General Material Information - Copper C101/CW004A

This grade of material refers to coppers of 99.9% purity and is used in a wide range of engineering applications.

After Silver, Copper is the next best material used for conducting electricity. Since it also has a high thermal conductivity, this material is a good choice for use in conductor and electrical applications. Copper also has good mechanical properties in terms of toughness, ductility, impact strength and is also malleable.

The machinability of this grade of copper is rated as 20. To give context to this, a CZ121 Free machining brass is rated to approximately 100. The hot and cold working performance of C101 Copper is given as excellent. Work hardening effects set in relatively slowly, and the material can be annealed in neutral and oxidising atmospheres. Heat treatments such as this can be carried out by a rapid cooling process after heating to 370 to 650 degrees C.

The corrosive resistance of this material can be described as either good or excellent in most environmental conditions, except those containing ammonia ions.

C101/CW004A can be easily soldered, brazed and butt welded. Other welding processes are not recommended.
