Copper ferrules of makeup brushes

 Besides aluminum ferrule, copper ferrule is also an option for makeup brushes, especially for top end makeup brushes. Professional makeup artists or purchasers know that copper ferrule is thicker/heavier/durable/more shinning than aluminum ferrule, but during OEM makeup brushes, price is an important concern, the makeup brushes with copper ferrule is much expensive than aluminum ferrule. And even the same copper ferrule raw material, if different thickness and process, the price will vary. So at the beginning of custom makeup brushes, customers should clarify their exact demands on the copper ferrule, so that the makeup brush manufacturers can quote accurate price and provide qualified makeup brushes accordingly. In this article, we will briefly introduce the thickness and process of copper ferrule, as well as its difference with aluminum ferrule, for customers’ reference during OEM makeup brushes.

The following is a detailed description of the regular thickness, thickened thickness and processing technology of the makeup brush copper ferrule:
 
►Thickness

Regular thickness: 0.4mm～0.6mm
Features：

1. Suitable for mid-to-high-end makeup brushes, taking into account weight, hand feel and strength.
2. Copper's natural ductility is better than aluminum, and it is suitable for complex shapes (such as embossment and carving).

Applications: ordinary high-end makeup brushes, art design makeup brushes
 

Thickened Thickness:0.7mm～1.0mm (customized requirements can reach 1.2mm)
Features：

1. Heavy texture, strong resistance to deformation, suitable for large-sized brush handles or products that need to be used for a long time.
2. Surface treatment (such as gold plating, antique aging) has a more lasting effect.

Applications: luxury makeup brushes, collection-level products, customized packaging that requires hand-carving.

 
►Processing

Raw material selection
Material:

1. H65 brass (copper-zinc alloy, containing 65% copper) is commonly used, which combines ductility and strength.
2. For high-end products, can choose phosphor bronze (more corrosion-resistant but expensive).

State: soft state (O state) or semi-hard state (H02), select according to molding requirements.
 
Stamping

1. Cold stamping: The copper strip is stamped into a tubular blank through a continuous die (the springback of the copper material needs to be controlled).
2. Stretching process: 3 to 4 stretching steps are performed to gradually adjust the uniformity of the tube diameter and wall thickness (copper has high ductility, can reduce the number of annealing times).

Annealing treatment

1. Temperature: 450℃～600℃ (copper recrystallization temperature is relatively high, so precise temperature control is required).
2. Time: 1～3 hours (adjusted according to the composition and thickness of the copper material to eliminate work hardening).
3. Protective atmosphere: nitrogen or vacuum annealing to prevent oxidation and discoloration of the copper surface.

 
Surface treatment

Polishing: Mechanical polishing or electrolytic polishing to achieve mirror or matte effect.
Plating:

1. Nickel plating/chrome plating: basic anti-corrosion layer (3-5μm).
2. Gold plating/rose gold plating: decorative plating (0.5~2μm).

Oxidation aging: Chemical oxidation produces a verdigris or antique blackening effect (protective paint needs to be sprayed).
Spraying: Clear paint or colored paint (to protect the original color of copper or to achieve special colors).

 
Finishing and assembly

1. Engraving/etching: Laser engraving logo or pattern (power must be controlled to avoid burning through thin walls).
2. Welding/riveting: copper ferrule and brush head connection (copper conducts heat quickly, high temperature deformation must be avoided).
3. Sealing: crimping or thread sealing (copper is soft, strength must be controlled to prevent deformation).

 
Quality inspection

1. Wall thickness uniformity: X-ray or ultrasonic inspection (copper tubes are prone to uneven local stretching).
2. Corrosion resistance: Salt spray test (copper itself is corrosion-resistant, but the coating needs to pass a 24-72 hour test).
3. Appearance consistency: Colorimeter to detect coating color, visual inspection of surface defects.

 
►Process Differences Between Copper Ferrules and Aluminum Ferrules

Item	Copper	Aluminum
Annealing temperature	450℃～600℃	300℃～400℃
Difficulty of surface treatment	Easy to oxidize, requiring more stringent anti-rust pretreatment	The oxide film is stable and anodizing is more convenient
Forming springback	Low rebound rate and easy to control dimensional accuracy	High rebound rate, multiple corrections are required
Cost	High raw material cost (about 3 to 4 times that of aluminum)	Low cost, suitable for mass production
Environmental protection	100% recyclable, but electroplating wastewater contains heavy metals	Recyclable, low anodizing pollution

 
 
►Key process considerations

Anti-oxidation control:
During the whole process, bare copper should be kept away from moisture. Anti-rust oil or temporary passivation can be applied during the intermediate process.
 
Electroplating adhesion:
The copper surface needs to be primed with nickel (1-2μm) to prevent copper ion migration from causing the coating to peel off.
 
Risks of thin-wall processing:
When the thickness is less than 0.4mm, it is easy to crack during stamping, so it is necessary to use soft copper and increase the number of annealing times.
 
Cost optimization:
Using copper-clad steel or copper-aluminum composite pipes can reduce costs, but will sacrifice the texture of pure copper.

 
►Industry Trends

1. Lightweight design: Ultra-thin copper tubes (0.3mm) are strengthened by increasing the zinc content.
2. Retro craft revival: Hand-hammering, acid etching and other processes are applied to limited edition products.
3. Environmentally friendly alternatives: Cyanide-free electroplating and water-based paint spraying technologies are gradually becoming popular.

 
►The advantages and disadvantages of copper ferrules
 

Advantages	Disadvantages
High-quality texture, suitable for luxury goods	High cost
Good ductility, can achieve complex shapes	Easy to oxidize during processing, need additional protection
Corrosion resistance is better than ordinary steel	The electroplating process is complex (multi-layer plating is required)
Good thermal conductivity, suitable for brushes that need to dry quickly	Heavy and less portable

 
 
The above process parameters can be adjusted according to specific requirements (such as copper pipe diameter, surface effect).

Innovation direction of makeup brush manufacturers

 The makeup brush manufacturers can keep innovation through the following aspects:
