Black Aluminum Pop Rivets
Weight Range ： 0.5g–500kg
Dimensional tolerance ： ±0.1mm
Black aluminum pop rivets are the preferred fasteners in modern assemblies. It combines performance with beauty. The rivet body is made of aluminum alloy with a density of only 2.7 grams per cubic centimeter. Compared with steel rivets of the same size, it can achieve a weight reduction of up to 67%. This is crucial for industries such as aerospace and new energy vehicles. At the same time, it is hard-anodized. Its standard salt spray test time exceeds 72 hours. This ensures long-term durability outdoors or in wet environments.
The product is equally reliable in terms of mechanical properties. Take the commonly used 3.2 mm specification as an example. The minimum tensile force of a single rivet is 0.38 kN, and the minimum shear force is 0.25 kN. This meets the strength requirements of most sheets and frames. The partially enclosed design also has good sealing properties. It can withstand air pressure tests up to 0.3 bar and effectively prevents water and dust penetration. In the long term, its excellent durability can reduce maintenance requirements by more than 70%, bringing stable value to the project.

Benefits
Lightweight advantage
The rivet body of black aluminum blind rivets is made of aluminum alloy. Its density is only 2.7g/cm³. Compared with steel rivets of the same size, the weight is reduced by about 67%. This weight loss is crucial.
It can reduce the weight of the overall structure. This can help improve energy efficiency or extend device life. Therefore, it is widely used in vehicle manufacturing and other fields.
Strength to weight ratio
Although its texture is light, its mechanical properties are very strong. Take 3.2mm rivets made of A5056 material as an example. Its minimum shear force can reach 0.25kN.
The minimum tensile strength can reach 0.38kN. It can provide sufficient structural strength while achieving lightweight. Ideal for applications such as sheet joining and frame assembly.
Excellent shock resistance
When high-quality rivets are riveted, the rivet body expands evenly. Its radial expansion rate can reach 15%-20%. This fully fills the differential holes. Effectively reduce looseness caused by tolerances.
This provides excellent resistance to vibration and fatigue. Very suitable for vibration environments such as vehicles and mechanical equipment.
Reliable sealing ability
Some high-quality products have a "closed" design. After riveting, the tail will form a completely sealed end. According to the DIN 7337 standard test, it can effectively prevent water and dust penetration.
For example, a 4.8mm diameter rivet can withstand 0.3 bar air pressure without leaking. It is very suitable for scenarios such as boxes and outdoor electrical cabinets that need to be sealed.

♦♦♦ F A Q ♦♦♦
Are these rivets made of pure aluminum? Is it strong enough?
- It is not pure aluminum. It is a high-strength A5056 aluminum alloy with high magnesium content. The strength and corrosion resistance are much better than ordinary aluminum, and conventional structural connections are completely sufficient.
Will the black color fade?
- The high-quality ones are hard anodized, not spray painted. It basically does not fade under normal use, and is wear-resistant and corrosion-resistant. Scratching it with a key may leave a mark, but it won't fall off in large pieces.
What size should I buy?
- The key is to look at two numbers: diameter and clamping thickness. Tell me the total thickness of material you want to join and we will recommend a specific length. Commonly used diameters are 3.2mm and 4.0mm.
Why are the prices so different?
- The main difference lies in the material (whether it is true A5056), surface treatment process (whether it is true anodizing), and the nail core locking structure. The ones that are too cheap are probably recycled aluminum or regular spray paint.
Are there samples? Can you give it a try?
- A small amount of samples can be provided for free. It is recommended that you use your own materials and tools to test it yourself. The riveting effect and strength are most intuitive.
What is the minimum order quantity?
- Regular specifications usually require a minimum order of 1 box (100 pieces) or 1 kg. Supports mixed batches of multiple specifications, as long as the total amount reaches a certain amount.
How long does it take to ship the order after placing the order?
- Regular specifications are in stock and usually shipped within 1-3 working days. Special sizes need to be customized, which usually takes 7-15 days.
If there is a problem with it, can it be returned or exchanged?
- Returns and exchanges are supported as long as it is unused and the packaging is intact. If there is a product quality problem (such as cracking in large quantities, failure to tighten), we will be responsible for the return and exchange and bear the shipping costs.
