Copper Alloy 110, often referred to as electrolytic tough pitch (ETP) copper, is a distinctive option for crafting address numbers and sign letters. Here are some features, benefits, and potential considerations:

**Features:**
1. **Excellent Ductility:** This alloy exhibits remarkable ductility, making it easy to shape and form into intricate designs. This feature is particularly valuable for creating custom address numbers and sign letters with unique aesthetics.

2. **Distinctive Color and Patina:** Copper Alloy 110's warm reddish-brown color provides a unique and inviting visual appeal. Over time, copper naturally develops a characteristic patina, transitioning from its original color to a range of greenish hues, adding depth and character to your design.

**Benefits:**
1. **Timeless Aesthetic:** The warm, rich color of Copper Alloy 110 adds a touch of elegance and timelessness to address numbers and sign letters. The evolving patina enhances the visual appeal, creating an engaging visual story over the years.

2. **Sustainability:** Copper is a recyclable material, aligning with sustainability goals. Choosing Copper Alloy 110 for your address numbers and sign letters can contribute to eco-friendly design choices.

**Considerations:**
1. **Patina Development:** While the patina can enhance the aesthetics of Copper Alloy 110, it's important to note that the process can take time and might not be uniform. Some areas might develop the patina faster than others >>> To have your copper numbers or letters delivered with a PATINA finish, please see the links nearby.

2 **Cost:** Copper Alloy 110 tends to be more expensive than some other materials due to its unique properties and aesthetic appeal.

In summary, Copper Alloy 110 presents a set of distinctive features and benefits that make it an timeless choice for crafting address numbers and sign letters. The material's timeless aesthetic and customization possibilities cater to the preferences of architects, designers, and homeowners seeking a unique and enduring design solution.

The "reverse channel" or "fabricated channel" method is a sophisticated and lower carbon footprint method of crafting dimensional sign letters. It combines cutting-edge CNC technology to shape the faces with the artistry of skilled silversmiths who shape the sides of the letters. Silver solder or other types of solder are used to securely attach the faces and returns. The right angle meeting point of the two surfaces are then blended to achieve either a satin brushed or mirror polished finish, resulting in meticulously crafted letters that are both visually appealing and durable.

**Lower Carbon Footprint:**
The method described below is a "greener" use of materials as the end product is hollow, using a fraction of the metal that would normally be consumed for solid letters and numbers of this size. The training and dexterity required from the artisanal standpoint is where this manufacturing method gets its most meaningful inputs.

**CNC Technology for Cutting Faces:**
- CNC technology plays a pivotal role in this process by precisely cutting the faces of the letters and numbers. This ensures accuracy and consistency in the shapes and dimensions, forming the foundation of the letter design.

**Handwork by Trained Silversmiths:**
- Skilled silversmiths, who possess specialized expertise, are essential for shaping the sides or "returns" of the letters. Their craftsmanship becomes particularly crucial for shorter, smaller characters with narrow strokes and deep returns, where manual shaping is more intricate, ensuring the letters achieve a seamless and visually appealing three-dimensional appearance.

**Soldering and Fastening:**
- Inside the open back of each letter, silver solder or other types of solder are applied to securely fasten the faces to the returns. This soldering process reinforces the structural integrity of the letters.

**Blending Faces and Returns:**
- To create a harmonious transition between the faces and returns of the letters, the surfaces are meticulously blended together. This process involves using abrasive tools like a Dynafile and/or other gentler abrasives, depending on whether a satin grained (#4) or mirror polished (#8) finish is specified.

**Attaching Threaded Stud Locations:**
- Depending upon the overall size or complexity of the number or letter shape, 3 to 5 nuts are attached with solder to metal straps and in turn secured to the open backs of each number or letter with solder. These accept the threaded studs that come with each order and over which the spacer tubes are placed prior to installing in the holes drilled into the mounting surface (wall, door, fence post, etc). We also offer alternate attachment/affixing axes such as bottom mount or top mount, as well as offering enclosed backs to match the faces and returns should they be visible from the back.

**Creating the Drilling Pattern:**
The hole pattern for each number is transferred carefully to a single paper drilling pattern for the whole address set. The look of this is based upon your approved layout for the set – whether vertical, monospaced, diagonal or other tracked and kerned specifications – which you have relayed to us.
