M2 M2.5 M3 Titanium Alloy Male And Female 7/8 7/16 1/2 Hex Head Metal Standoff Metal standoff

Product Description:
What is a standoff? As the name suggests, the standoff is a screw with internal thread at one end and external thread at the other end, and the broad sense of the standoff also includes screws with internal threads at both ends. Its appearance is hexagonal, play a role in fastening and isolating, because it is generally made of hexagonal copper rods as raw materials, so the standoff is also known as copper column, hexagonal copper column, copper isolation column or copper gasket column.
The use of copper columns. Hexagonal screws are mainly used in computers, circuit boards and other industries, when one end is screwed into the locked object, the hexagonal column is exposed to the outside, which can fix or isolate other objects.
The main specifications of standoff are M3, M4, M5, M6, M8, M10, etc., and the specifications of the hexagonal column are 5, 6, 8, 10, 12, 15 mm, etc., of which the M3 series is the most. Materials in addition to copper and stainless steel, there are fast cutting steel.

Hexagonal studs are also known as yin and yang studs, it is one end of the internal thread and one end of the external thread, but are hexagonal, can play a role in fastening and isolation.
Mostly used in computers, circuit boards and other industries, when used, when one end is screwed into the workpiece being fastened, the hexagonal column is exposed on the surface, can be fixed or isolated from other workpieces. Such as in the computer mainframe, the external thread can be connected to the motherboard inside the mainframe, the internal thread can be isolated from the motherboard and sheet metal shell.

Applications:

Brass is an alloy composed of copper and zinc, brass composed of copper and zinc is called ordinary brass, if it is a variety of alloys composed of more than two elements is called special brass. Brass has strong wear resistance, brass is often used in the manufacture of valves, water pipes, air-conditioning inside and outside the machine connecting pipes and radiators.
Ordinary brass is a copper-zinc binary alloy, its zinc content varies widely, so its room temperature organisation is also very different. According to the Cu-Zn binary state diagram, the room temperature organisation of brass has three kinds: brass with zinc content below 35%, the microstructure at room temperature consists of a single-phase α solid solution, known as α brass; zinc content in the range of 36% to 46% brass, the microstructure at room temperature consists of (α + β) two-phase composition, known as (α + β) brass (two-phase brass); zinc content More than 46% to 50% of the brass, room temperature microstructure is composed of only β phase, known as β brass.

Heat Treatment Specification

Hardness: O, 1/2H, 3/4H, H, EH, SH and so on;
Applicable standards: GB, JISH, DIN, ASTM, EN;

Special Brass
In the ordinary brass to add other alloying elements composed of multiple alloys known as special brass. The commonly added elements are lead, tin, aluminium, etc., which can be called lead brass, tin brass, aluminium brass accordingly. The purpose of adding alloying elements. The main purpose is to improve the tensile strength and processability.
Code: for ‘H + main plus element symbol (except zinc) + copper mass fraction + main plus element mass fraction + other elements mass fraction’ said.
For example: HPb59-1 indicates that the mass fraction of copper is 59%, the mass fraction of lead is 1%, and the balance is zinc lead brass.

Oxidation temperature and time for different steel parts:

1. High Strength-to-Weight Ratio
   Titanium alloys provide exceptional strength without adding excessive weight. This makes them ideal for applications where weight reduction is critical, such as in aerospace and automotive industries.
2. Exceptional Corrosion Resistance
   Titanium forms a stable oxide layer on its surface, protecting it from corrosion. This makes it highly resistant to rust, seawater, and harsh chemicals, ensuring long-term durability.
3. Biocompatibility
   Titanium is non-toxic and biocompatible, making it safe for use in medical implants and surgical instruments. It does not cause allergic reactions and is well-tolerated by the human body.
4. Thermal Stability
   Titanium alloys maintain their strength and integrity at high temperatures, making them suitable for applications in extreme thermal environments, such as aerospace engines.
5. Low Thermal Expansion
   Titanium has a low coefficient of thermal expansion, reducing the risk of loosening or failure under temperature fluctuations.
6. Non-Magnetic Properties
   Titanium alloy hardware is non-magnetic, making it suitable for use in environments where magnetic interference is a concern, such as MRI machines and electronic devices
